TRIzol Reagent RNA提取試劑

 

產(chǎn)品描述

TRIzol Reagent是一種即用型且操作迅捷的總RNA抽提試劑,適用樣本廣泛,包括人、動(dòng)物、植物、酵母或細(xì)菌來源的細(xì)胞和組織樣本。TRIzol Reagent是一種含酚、異硫氰酸胍和其他專利成分的單相溶液,有利于抽提分子量大小不一的各種RNA類型。TRIzol Reagent能夠良好的維持RNA完整性,因能高效抑制樣本勻漿過程中細(xì)胞破損和細(xì)胞組分溶解時(shí)釋放的RNase活性。TRIzol Reagent能夠同時(shí)處理大量樣本,且以優(yōu)化的方式一步法提取RNA,整個(gè)過程可在一小時(shí)內(nèi)完成。

TRIzol Reagent分離的總RNA無蛋白質(zhì)和DNA污染,適用于RT-PCR、Northern Blot、Dot Blotpoly(A)+篩選、體外翻譯、RNase保護(hù)分析和分子克隆等下游實(shí)驗(yàn)。

 

保存與運(yùn)輸方法

保存:2-8保存,至少一年有效。

運(yùn)輸:冰袋運(yùn)輸。

 

注意事項(xiàng)

1   所有離心管、槍頭以及相關(guān)溶液都必須無RNase污染。對(duì)于塑料制品、玻璃和金屬器皿、實(shí)驗(yàn)儀器等可使用固相RNase清除劑去除RNase,或者用含0.01% DEPC的去離子水浸泡過夜,之后高壓滅菌、烘干。對(duì)于實(shí)驗(yàn)溶液可使用液相RNase清除劑來處理或用DEPC處理水來配制。

2   對(duì)新鮮組織或細(xì)胞樣本的抽提效果通常優(yōu)于凍存的組織或細(xì)胞,由于組織或細(xì)胞凍融過程中可能存在一些RNase釋放出來并酶切樣品。若是不能及時(shí)提取RNA,推薦先加入適量TRIzol Reagent,之后裂解樣品后再凍存。

3   TRIzol Reagent含有毒物質(zhì),請(qǐng)?jiān)诓僮鬟^程中注意好防護(hù)工作,戴好手套和護(hù)眼罩,避免皮膚接觸。在通風(fēng)櫥內(nèi)完成操作,避免呼吸道吸入。

4  為了您的安全和健康,請(qǐng)穿實(shí)驗(yàn)服并戴一次性手套操作。

 

使用方法

1.  需要自行準(zhǔn)備的材料

水浴鍋或微量恒溫儀(Heat block

異丙醇

75%乙醇

0.5% SDSRNase-free水或RNase-free水或DEPC處理水

【可選】RNase-free的糖原(核酸助沉劑)

2.  樣本要求

【重要】:樣本收集后立即進(jìn)行RNA分離,或樣本收集后立即凍存樣本并保存在-80或液氮中直至RNA提取。

樣本類型

mlTRIzol Reagent處理的起始樣本量

組織(新鮮組織或保存在RNAlater等穩(wěn)定液內(nèi)的組織)

50~100mg組織

單層生長的細(xì)胞

1×105~1×107單細(xì)胞層(35mm培養(yǎng)皿,10cm2

懸浮生長的細(xì)胞

5-10×106個(gè)細(xì)胞(動(dòng)植物或酵母來源)或1×107個(gè)細(xì)胞(細(xì)菌來源)

3. 樣本準(zhǔn)備與分相

3.1 根據(jù)起始材料用TRIzol Reagent裂解和勻漿樣本。

組織樣本

按比例每50~100mg 組織加1ml TRIzol Reagent,之后用合適的方法進(jìn)行勻漿。通常用50~100mg組織即可獲得足量的RNA,滿足絕大多數(shù)下游實(shí)驗(yàn)。加入過量組織或過少TRIzol都容易導(dǎo)致RNA提取失敗。

a對(duì)于研缽研磨:將液氮凍存組織,放到研缽中研磨成粉末,之后加入1ml TRIzol,繼續(xù)研磨至組織完全裂解【研磨要迅速,最好不要超過1min】。

b對(duì)于玻璃勻漿器勻漿:加入1ml TRIzol上下手動(dòng)勻漿組織10~15次。

c對(duì)于機(jī)械勻漿器:將組織放入塑料管內(nèi),將塑料管置于冰浴燒杯內(nèi),加入1ml TRIzol,將分散器頭垂直插入管內(nèi)與組織直接接觸,設(shè)置轉(zhuǎn)速12,000~20,000 rpm,上下移動(dòng)試管10~20次,直至組織完全打散,無明顯可見大塊即可。

單層生長的細(xì)胞

吸盡培養(yǎng)基,之后往35mm培養(yǎng)皿(10cm2)內(nèi)加入1ml TRIzol Reagent,晃動(dòng)3~5次,再用移液槍上下吹打3~5次,使其充分裂解?!景凑?/span>10cm2培養(yǎng)面積加入1ml TRIzol加量。比如:六孔板每孔加入1ml TRIzol,12孔板每孔加0.5ml TRIzol

  懸浮生長的細(xì)胞

離心收集細(xì)胞,吸盡上清,每5-10×106個(gè)細(xì)胞(動(dòng)植物或酵母來源)或1×107個(gè)細(xì)胞(細(xì)菌來源)加入1ml TRIzol Reagent【加入TRIzol前不要清洗細(xì)胞,否則會(huì)增加mRNA降解的可能性】。用槍吹打幾次或適當(dāng)渦旋,使其充分裂解。某些酵母和細(xì)菌如裂解不充分,可用勻漿器勻漿,使其完全裂解。

【注意】:樣本體積不要超過加入TRIzol體積的10%。 

3.2 特殊樣本處理【可選】:對(duì)于某些富含蛋白,多糖或脂肪的樣本,經(jīng)TRIzol Reagent裂解后可能會(huì)有不溶物或油脂狀漂浮物出現(xiàn)。此時(shí)需12,000g 4離心10min,之后吸取澄清的上清液至一新的離心管中。

3.3 室溫孵育5min,使得核蛋白體完全分解。

3.4 按照每1ml TRIzol Reagent加入0.2ml 氯仿,蓋緊蓋子。渦旋混勻或用手劇烈晃動(dòng)15s,室溫孵育2~3min

3.5 12,000g 4離心15min。離心后混合物分為三層:下層酚氯仿層,中間層,和上層無色的水相層。RNA無一例外的停留在水相層中。水相層的容量約為所加TRIzol Reagent體積的60%。用槍吸取上層無色水相到一新的離心管中,避免吸到任何中間層或下層成分。

【注意】:如果希望分離DNA和蛋白,請(qǐng)保留中間層和有機(jī)層。

4.      RNA分離

4.1    RNA的沉淀:

a【可選】如果起始樣本量比較少(<106個(gè)細(xì)胞或<10mg組織),加入5-10μg RNase-free的糖原作為核酸助沉劑到水相中。

b按每ml起初TRIzol Reagent加入0.5ml異丙醇,顛倒數(shù)次混勻,室溫沉淀10min。如果希望提取microRNA等小RNA,推薦-70沉淀過夜。c12,000g 4離心10min,在管底可見RNA沉淀,棄上清。

4.2    RNA的清洗:

a按每ml起初TRIzol Reagent加入1ml 75%乙醇重懸沉淀?!咀ⅲ?/span>RNA75%乙醇中-20至少保存1年,4至少1周】;

b低速漩渦或顛倒混勻,于7,500g 4離心5min,棄上清。再用離心機(jī)甩一下(>5,000rpm, 離心1秒),小心吸盡液體。

c操作的最后,簡單干燥RNA沉淀(空氣干燥或真空干燥5~10min)。不要在真空管里離心干燥RNA。尤為重要的是,不能讓RNA沉淀完全干燥,否則會(huì)極大的降低其可溶性。部分溶解的RNA樣本的A260/A280比值<1.6。

4.3    RNA的溶解:用20~50μl RNases水或含0.5% SDS的無RNases水溶解RNA,用槍上下吹打2~3次,使其充分溶解,置于-70保存或直接用于后續(xù)實(shí)驗(yàn),如果后續(xù)要做酶切反應(yīng)請(qǐng)勿用SDS。

【注意】:對(duì)于肝臟、胰腺、腎臟等RNase含量較高的組織,沉淀可用100%去離子甲酰胺溶解。

5.      RNA產(chǎn)量的測定

5.1    用無RNase水稀釋RNA,之后測定在260nm280nm的吸收值。

5.2    使用公式A260×稀釋倍數(shù)×40= μg RNA/ml。

5.3    計(jì)算A260/A280比值,比值在1.8~2.0之間視為純度較高,濃度>4 μg/ml的樣品適用于分光光度計(jì)測定。

5.4    進(jìn)行甲醛變性瓊脂糖電泳,確定RNA的完整性和污染情況。

EZ poly™RNA轉(zhuǎn)染試劑(NBS9425) 

一:轉(zhuǎn)染效率低

影響細(xì)胞轉(zhuǎn)染效率的因素有很多。首先,與所轉(zhuǎn)染細(xì)胞有關(guān),有的細(xì)胞容易轉(zhuǎn)染,如HeLa、B16F10、293T等。有的細(xì)胞不易轉(zhuǎn)染,如4T1、NIH3T3、BMDC等。其次,與轉(zhuǎn)染試劑的用量及與DNA的比例有關(guān),在最佳的轉(zhuǎn)染比例附近可以達(dá)到最佳的轉(zhuǎn)染效果。最后,沒有使用最適宜的細(xì)胞密度,應(yīng)根據(jù)各種轉(zhuǎn)染試劑的說明書中推薦的細(xì)胞密度進(jìn)行細(xì)胞接種,更有利于提高轉(zhuǎn)染效率。


二:轉(zhuǎn)染效果不穩(wěn)定,不能重現(xiàn)

轉(zhuǎn)染效果不穩(wěn)定一般與兩個(gè)因素緊密相關(guān),一個(gè)是轉(zhuǎn)染試劑的穩(wěn)定性,另一個(gè)是基因的穩(wěn)定性。轉(zhuǎn)染試劑應(yīng)按照說明書建議的保存溫度及條件進(jìn)行保存。如使用脂質(zhì)體類的轉(zhuǎn)染試劑,則不建議反復(fù)凍融,會(huì)引起該轉(zhuǎn)染試劑結(jié)構(gòu)上的變化?;蛉缍虝r(shí)間內(nèi)連續(xù)使用,可放置于4℃保存。若超過10天不使用,建議置于-20℃或-80℃長期儲(chǔ)存以降低核酸的降解速度。


三:細(xì)胞毒性大

導(dǎo)致轉(zhuǎn)染時(shí)細(xì)胞毒性大的因素有很多,例如DNA的用量過大、轉(zhuǎn)染試劑的用量過大、轉(zhuǎn)染時(shí)細(xì)胞狀態(tài)較差以及培養(yǎng)基中抗生素的加入等。建議嚴(yán)格按照所選擇轉(zhuǎn)染試劑的說明書進(jìn)行操作,以避免細(xì)胞毒性大的問題。

四:沒有生成高效率的DNA轉(zhuǎn)染試劑復(fù)合物

沒有生成高效復(fù)合物的因素有很多。首先,可能是沒有選對(duì)合適的轉(zhuǎn)染試劑。挑選轉(zhuǎn)染試劑時(shí)應(yīng)考慮基因的種類及分子量等因素。其次,有的轉(zhuǎn)染試劑對(duì)血清的影響很大,應(yīng)在無血清情況下進(jìn)行轉(zhuǎn)染。使用諾寧生物的EZ poly™  系列轉(zhuǎn)染試劑無需考慮血清對(duì)轉(zhuǎn)染體系的影響,可在含血清培養(yǎng)基中進(jìn)行轉(zhuǎn)染。

五:使用錯(cuò)誤的轉(zhuǎn)染操作步驟

無論使用哪一款基因轉(zhuǎn)染試劑,都應(yīng)嚴(yán)格按照該轉(zhuǎn)染試劑的說明書進(jìn)行操作,其中包括轉(zhuǎn)染試劑的用量、基因用量、最佳轉(zhuǎn)染比例、孵育時(shí)間、檢測時(shí)間等重要因素。

六:轉(zhuǎn)染試劑有時(shí)呈云霧狀渾濁

如發(fā)現(xiàn)轉(zhuǎn)染試劑出現(xiàn)云霧狀渾濁應(yīng)立即聯(lián)系客服人員。基因轉(zhuǎn)染試劑一般都呈清澈透明狀態(tài),呈云霧狀渾濁可能是由于轉(zhuǎn)染試劑發(fā)生了污染或儲(chǔ)存溫度太低,請(qǐng)務(wù)必按照試劑說明書要求的溫度進(jìn)行儲(chǔ)存。如出現(xiàn)此現(xiàn)象,建議溫浴10分鐘后,觀察是否澄清。


七:轉(zhuǎn)染復(fù)合物出現(xiàn)沉淀

當(dāng)轉(zhuǎn)染試劑和基因的用量都高于說明書用量,或復(fù)合物的孵育體系體積小于說明書建議時(shí),由于體系中過量的電荷發(fā)生了聚集會(huì)導(dǎo)致體系中的復(fù)合物出現(xiàn)沉淀。建議要嚴(yán)格參考說明書的用量進(jìn)行轉(zhuǎn)染。


八:siRNA轉(zhuǎn)染時(shí),基因沉默效率不夠高

影響siRNA沉默效率的因素很多,如基因本身是否被環(huán)境中的RNA酶污染降解?或所使用的細(xì)胞是否為難轉(zhuǎn)染細(xì)胞?以及是否按照說明書建議的用量進(jìn)行了操作等。首先應(yīng)該選擇合適的siRNA基因轉(zhuǎn)染試劑,確保細(xì)胞密度在60-70%之間,并嚴(yán)格按照說明書建議的用量去使用操作。


九:DNA-siRNA共轉(zhuǎn)染時(shí),基因沉默效率不夠高

當(dāng)細(xì)胞同時(shí)轉(zhuǎn)染DNA和siRNA時(shí),建議使用分別轉(zhuǎn)染的方式進(jìn)行。即使用基因轉(zhuǎn)染試劑分別與DNA和siRNA進(jìn)行復(fù)合,再將兩個(gè)復(fù)合物體系分兩次分別加入到同一個(gè)裝有細(xì)胞的實(shí)驗(yàn)孔中。因DNA和RNA的轉(zhuǎn)染機(jī)理不相同,如只想使用一種轉(zhuǎn)染試劑同時(shí)轉(zhuǎn)染兩種基因,建議一定要使用通用型基因轉(zhuǎn)染試劑,如EZ poly™ 系列的DNA/RNA產(chǎn)品,即可以轉(zhuǎn)染DNA又可以轉(zhuǎn)染RNA。

EZ poly™DNA/RNA轉(zhuǎn)染試劑(NBS4926)

一:轉(zhuǎn)染效率低

影響細(xì)胞轉(zhuǎn)染效率的因素有很多。首先,與所轉(zhuǎn)染細(xì)胞有關(guān),有的細(xì)胞容易轉(zhuǎn)染,如HeLa、B16F10、293T等。有的細(xì)胞不易轉(zhuǎn)染,如4T1、NIH3T3、BMDC等。其次,與轉(zhuǎn)染試劑的用量及與DNA的比例有關(guān),在最佳的轉(zhuǎn)染比例附近可以達(dá)到最佳的轉(zhuǎn)染效果。最后,沒有使用最適宜的細(xì)胞密度,應(yīng)根據(jù)各種轉(zhuǎn)染試劑的說明書中推薦的細(xì)胞密度進(jìn)行細(xì)胞接種,更有利于提高轉(zhuǎn)染效率。


二:轉(zhuǎn)染效果不穩(wěn)定,不能重現(xiàn)

轉(zhuǎn)染效果不穩(wěn)定一般與兩個(gè)因素緊密相關(guān),一個(gè)是轉(zhuǎn)染試劑的穩(wěn)定性,另一個(gè)是基因的穩(wěn)定性。轉(zhuǎn)染試劑應(yīng)按照說明書建議的保存溫度及條件進(jìn)行保存。如使用脂質(zhì)體類的轉(zhuǎn)染試劑,則不建議反復(fù)凍融,會(huì)引起該轉(zhuǎn)染試劑結(jié)構(gòu)上的變化?;蛉缍虝r(shí)間內(nèi)連續(xù)使用,可放置于4℃保存。若超過10天不使用,建議置于-20℃或-80℃長期儲(chǔ)存以降低核酸的降解速度。


三:細(xì)胞毒性大

導(dǎo)致轉(zhuǎn)染時(shí)細(xì)胞毒性大的因素有很多,例如DNA的用量過大、轉(zhuǎn)染試劑的用量過大、轉(zhuǎn)染時(shí)細(xì)胞狀態(tài)較差以及培養(yǎng)基中抗生素的加入等。建議嚴(yán)格按照所選擇轉(zhuǎn)染試劑的說明書進(jìn)行操作,以避免細(xì)胞毒性大的問題。

四:沒有生成高效率的DNA轉(zhuǎn)染試劑復(fù)合物

沒有生成高效復(fù)合物的因素有很多。首先,可能是沒有選對(duì)合適的轉(zhuǎn)染試劑。挑選轉(zhuǎn)染試劑時(shí)應(yīng)考慮基因的種類及分子量等因素。其次,有的轉(zhuǎn)染試劑對(duì)血清的影響很大,應(yīng)在無血清情況下進(jìn)行轉(zhuǎn)染。使用諾寧生物的EZ poly™  系列轉(zhuǎn)染試劑無需考慮血清對(duì)轉(zhuǎn)染體系的影響,可在含血清培養(yǎng)基中進(jìn)行轉(zhuǎn)染。

五:使用錯(cuò)誤的轉(zhuǎn)染操作步驟

無論使用哪一款基因轉(zhuǎn)染試劑,都應(yīng)嚴(yán)格按照該轉(zhuǎn)染試劑的說明書進(jìn)行操作,其中包括轉(zhuǎn)染試劑的用量、基因用量、最佳轉(zhuǎn)染比例、孵育時(shí)間、檢測時(shí)間等重要因素。

六:轉(zhuǎn)染試劑有時(shí)呈云霧狀渾濁

如發(fā)現(xiàn)轉(zhuǎn)染試劑出現(xiàn)云霧狀渾濁應(yīng)立即聯(lián)系客服人員?;蜣D(zhuǎn)染試劑一般都呈清澈透明狀態(tài),呈云霧狀渾濁可能是由于轉(zhuǎn)染試劑發(fā)生了污染或儲(chǔ)存溫度太低,請(qǐng)務(wù)必按照試劑說明書要求的溫度進(jìn)行儲(chǔ)存。如出現(xiàn)此現(xiàn)象,建議溫浴10分鐘后,觀察是否澄清。


七:轉(zhuǎn)染復(fù)合物出現(xiàn)沉淀

當(dāng)轉(zhuǎn)染試劑和基因的用量都高于說明書用量,或復(fù)合物的孵育體系體積小于說明書建議時(shí),由于體系中過量的電荷發(fā)生了聚集會(huì)導(dǎo)致體系中的復(fù)合物出現(xiàn)沉淀。建議要嚴(yán)格參考說明書的用量進(jìn)行轉(zhuǎn)染。


八:siRNA轉(zhuǎn)染時(shí),基因沉默效率不夠高

影響siRNA沉默效率的因素很多,如基因本身是否被環(huán)境中的RNA酶污染降解?或所使用的細(xì)胞是否為難轉(zhuǎn)染細(xì)胞?以及是否按照說明書建議的用量進(jìn)行了操作等。首先應(yīng)該選擇合適的siRNA基因轉(zhuǎn)染試劑,確保細(xì)胞密度在60-70%之間,并嚴(yán)格按照說明書建議的用量去使用操作。

SCICONS Mouse anti double-stranded RNA (K2) 小鼠抗雙鏈RNA單克隆抗體 (K2)

Mouse anti double-stranded RNA (K2)

Catalog number: 10030010/10030005

Clone K2
Isotype IgM kappa
Product Type Monoclonal Antibody
Units 10 ml/5 ml
Host Mouse
Application dsRNA-immunoblotting
ELISA
Immunofluorescence
Sandwich ELISA

Background
Over the past decade our double-stranded RNA (dsRNA)antibodies have been used extensively to detect and characterise plant and animal viruses with dsRNA genomes or intermediates. In addition, the anti-dsRNA antibodies can be used as a diagnostic tool to detect pathogens, including detection in paraffin-embedded fixed tissue samples (Richardson et al. 2010). K2 anti-dsRNA monoclonal antibody has an IgM isotype. K2 has primarily been used in ELISA and sandwich ELISA. Generally, K2 can be used in applications where an anti-dsRNA antibody with an isotype other than IgG (IgG2a) is required.

Synonyms: Mouse anti dsRNA

Source
Female DBA/2 mice were injected intraperitonially with a mixture of 50 ug L-dsRNA and 75 ug methylated bovine serum albumin, emulsified in complete Freund's adjuvant. After several boosts spleen cells were fused with Sp2/0-Agl4 myeloma cells to generate the hybridoma clone.

Product
The mAb K2 recognises double-stranded RNA (dsRNA) provided that the length of the helix is greater than or equal to 40 bp dsRNA. Recognition is independent of the sequence and nucleotide composition of the antigen. All naturally occurring dsRNAs investigated up to now (4050 species) as well as poly(I).poly(C) and poly(A).poly(U) have been recognised by K2. As described by Sch?nborn et al. K2 binds with high avidity to all dsRNAs investigated.

Formulation: Culture supernatant (RPMI, 5% fetal calf serum).

Concentration: Undiluted hybridoma supernatant

Applications
MAb K2 is primarily used for a sandwich ELISA to detect and quantitate (after calibration) dsRNA (see Sch?nborn et al.). For this application it should be diluted with PBS. It may also be advantageous to use K2 for immunofluorescence studies. The optimum working dilution of the antibody for any specific application should be established by titration. Not for use for clinical purposes. For in vitro use only.

Storage
After delivery antibodies should be aliquoted and stored at -20 ° or -70 °C. After adding 10 mM sodium azide undiluted antibody can also be stored at +4 °C for a short period of time. For long term storage the mAb should be kept frozen. Repeated freezing/thawing cycles should be avoided.

Shipping Conditions: The IgM mononclonal antibody K2 is only sold as hybridoma supernatant and shipped at ambient temperature.

Caution
This product is intended FOR RESEARCH USE ONLY, and FOR TESTS IN VITRO, not for use in diagnostic or therapeutic procedures involving humans or animals. It may contain hazardous ingredients. Please refer to the Safety Data Sheets (SDS) for additional information and proper handling procedures. Dispose product remainders according to local regulations.This datasheet is as accurate as reasonably achievable, but Exalpha Biologicals accepts no liability for any inaccuracies or omissions in this information.

Mouse anti double-stranded RNA (K1)

Catalog number: 10020200/10020500

Clone K1
Isotype IgG2a kappa
Product Type Monoclonal Antibody
Units 200 μg/500μg
Host Mouse
Application dsRNA-immunoblotting
ELISA
Flow Cytometry
Immuno-affinity-chromatography
Immunoblotting

Background
Over the past decade our double-stranded RNA (dsRNA)antibodies have been used extensively to detect and characterise plant and animal viruses with dsRNA genomes or intermediates. In addition, the anti-dsRNA antibodies can be used as a diagnostic tool to detect pathogens, including detection in paraffin-embedded fixed tissue samples (Richardson et al. 2010). The K1 monoclonal antibody recognises dsRNA with similar affinity to our widely used J2 antibody. It can be used for the histological and cytological detection of dsRNA in cells and tissues. It has proven especially useful as an alternative to J2 to resolve cross-reactions and/or remove unwanted background, in those rare experimental setups where J2 did not provide satisfactory results. K1 can be used to detect dsRNA intermediates of viruses as diverse as Hepatitis virus, Theiler’s murine encephalomyelitis virus or Japanese encephalitis virus. It has been for the detection of dsRNA in cultured cells and in fixed paraffin-embedded histological samples (see publications). If Poly I:C needs to be detected we highly using K1 rather than J2 because K1 has a much higher affinity for this synthetic polyribonucleotide (see Sch?nborn et al. 1991, Fig. 2). K1 has been used successfully in immunofluorescence microscopy, in flow cytometry (FACS) and in immunocapture methods (such as dot-blot and ELISA).

Synonyms: Mouse anti dsRNA

Source
Female DBA/2 mice were injected intraperitonially with a mixture of 50 ug L-dsRNA and 75 ug methylated bovine serum albumin, emulsified in complete Freund's adjuvant. After several boosts spleen cells were fused with Sp2/0-Agl4 myeloma cells to generate the hybridoma clone.

Product
The mAb K1 recognises double-stranded RNA (dsRNA) provided that the length of the helix is greater than or equal to 40 bp. dsRNArecognition is independent of the sequence and nucleotide composition of the antigen. All naturally occurring dsRNAs investigated up to now (40-50 species) as well as poly(I).poly(C) and poly(A).poly(U) have been recognised by K1. As described by Sch?nborn et al. K1 shows higher affinity to poly(I).poly(C) than to the other dsRNA antigens, although the difference of apparent binding constants may vary under different experimental conditions.

Formulation: The lyophilised sample should be reconstituted with 200 μl sterile distilled water. The mAb will then be in PBS without any stabilisers or preservatives at a concentration of 1 mgr/ml. As a result of the lyophilisation procedure, the reconstituted antibody may contain small amounts of denatured protein in the form of aggregates that may interfere with some applications such as immunohistochemistry (e.g. by giving high backgrounds). We therefore highly recommend centrifuging (microcentrifuge) the reconstituted antibody before use and using the supernatant.

Purification Method: Affinity chromatography on Protein A-agarose.

Purity: Gel electrophoretically pure IgG antibody.

Concentration: Concentration after reconstitution: 1.00 mg/ml as determined by A280 nm (A280 nm = 1.47 corresponds to 1 mg/ml antibody).

Applications
MAb K1 can be used for ELISA, dsRNA-immunoblotting, immuno-affinity-chromatography and in certain systems also for immunohistochemistry (see references). The optimum working dilution of the antibody for any specific application should be established by titration. Please note that nucleic acid separation prior to dsRNA-immunoblotting must be carried out by polyacrylamide gel electrophoresis, because the sensitivity of detection is considerably lower after blotting from agarose gels. Not for use for clinical purposes. For in vitro use only.

Storage
After reconstitution antibodies should be aliquoted and stored at -20 °C or -70 °C. After adding 10 mM sodium azide undiluted antibody can also be stored at +4 °C for a short period of time. For long term storage the mAb should be kept frozen. Repeated freezing/thawing cycles should be avoided. When kept lyophilized the product will remain stable for 10 years at -20 °C or -70°C.

Shipping Conditions: Ship at ambient tempeature.
