說明

一般描述

Antifoam C emulsion is an aqueous emulsion containing 30% active silicone. This silicone-based antifoam emulsionconsists of non-ionic emulsifiers different from those in antifoam emulsions B and Y-30. Antifoam C emulsion can be prediluted with 3-10 parts of cool water to aid in dispersion. Prediluted suspensions should be used immediately. Antifoam C emulsion is typically effective at 1-10 ppm. The flow properties of antifoam C emulsion are such that it can be pumped on an as-needed basis to a fermenter system with sufficient agitation to disperse the antifoam. Antifoam C emulsion can be used to regulate headspace foaming in mammalian cell culture bioreactors up to 30 ppm concentration.

應(yīng)用

Antifoam C emulsion has been used:

as a supplement in RO-H2O and a chemically defined culture medium to determinevolumetric mass transfer coefficient (kLa) of mammalian cell culture

as a component of feed medium,

as asteam-sterilized antifoaming agent in a biocontroller for pH-stat fed-batch cultivations

as a supplement in fed batch medium to mimic the typical large-scale cultivation conditions

說明

應(yīng)用

胰蛋白酶溶液已被用于角質(zhì)形成細(xì)胞的分離和染色。[1]在一項培養(yǎng)墨西哥鈍口螈的胚胎心肌細(xì)胞的研究中,它也被用作 CMF-Steinberg 溶液的成分,替代離心后的心臟組織。[2]

胰蛋白酶消化多肽時,胰蛋白酶:多肽使用約 1:100 至 1:20 的比例。該產(chǎn)品的典型用途是去除培養(yǎng)表面的貼壁細(xì)胞。使細(xì)胞脫離其底物所需的胰蛋白酶濃度主要取決于細(xì)胞類型和培養(yǎng)時間。胰蛋白酶也被用于細(xì)胞培養(yǎng)過程中的細(xì)胞重懸,蛋白質(zhì)組學(xué)研究中的蛋白質(zhì)消化和各種凝膠消化。其他的應(yīng)用還包括通過基于膜的技術(shù)評估結(jié)晶,并在一項研究中確定蛋白質(zhì)折疊速率和產(chǎn)量可能受到動力學(xué)陷阱存在的限制。

生化/生理作用

胰蛋白酶切割賴氨酸和精氨酸殘基 C 末端的肽。如果酸性殘基位于裂解站點兩側(cè),則該反應(yīng)的水解速率減慢,如果脯氨酸殘基位于裂解站點的羧基側(cè),則水解停止。胰蛋白酶活性的最適 pH 為 7-9。胰蛋白酶也可裂解氨基酸合成衍生物的酯鍵和酰胺鍵。向胰蛋白酶溶液中加入 EDTA,作為螯合劑,可中和鈣和鎂離子,使胰蛋白酶作用的肽鍵模糊。去除這些離子會增加酶的活性。

DFP、TLCK、APMSF、AEBSEF和抑肽酶等絲氨酸蛋白酶抑制劑可抑制胰蛋白酶。

一般描述

Replacement for MCHT24H48

MillicellHanging Cell Culture inserts with Polyethylene Terephthalate (PET) membrane are ideal for the growth and differentiation of various cell types. This individually sterile-packaged insert has an 0.4 μm membrane pore size and fits in most 24-well plastic tissue culture plates.

In plastic tissue culture plates, cells can access media only from their apical sides, but in Millicelltissue culture inserts, cells can access media from both their apical and basolateral sides. As a result, cell growth, structure, and function more closely mimic what occursin vivo.

The insert’s flanged design suspends it within the culture plate well and makes it possible to access both sides of the cell monolayer. Spaces between three protruding arms facilitate pipetting between the outside of the insert and the culture plate well.

品牌:bioGenous

產(chǎn)品介紹

Product Description:

Basement membranes are thin continuous layers of specialized extracellular matrices that form the interface on which epithelial, endothelial, or neuronal cells grow. Basement membranes also support muscle and Schwann cells of the peripheral nerves as they are found surrounding these cells. The bioGenousTM Organoid Culture ECM is a soluble form of basement membrane extracted and purified from the Engelbreth-Holm-Swarm (EHS) tumor. The major constituents of the bioGenousTM Organoid Culture ECM include laminin, collagen IV, entactin/nidogen, and heparin sulfate proteoglycan.

bioGenousTM Organoid Culture ECM is a reduced growth factor hydrogel that allows the complete control of the organoid culture microenvironment to allow for more consistent cell growth and reproducible experiments. It supports the growth and maintenance of human embryonic stem cells (hESCs) and tissue-derived stem cells, and for the in vivo study of both healthy and tumor organoids derived from various organs. bioGenousTM Organoid Culture ECM is compatible with all culture media and gels at temperatures above 10°C to form a reconstituted basement membrane.

10ml

 

8.5-9.0 mg/mL

-20,24 months

 

CAUTION: bioGenousTM Organoid Culture ECM will start to gel if kept above 10°C for an extended period. We recommend that you make aliquots and store at –80°C to –20°C to avoid repeated freeze-thaw cycles.

Directions for Use

1.    Start by thawing the bioGenousTM Organoid Culture ECM by submerging the vial in ice in a 4°C refrigerator, overnight.

2.    After the bioGenousTM Organoid Culture ECM has been completely thawed, gently swirl the vial to carefully mix the content of the vail on ice at all times.

3.    If working with small volumes make aliquots of the bioGenousTM Organoid Culture ECM by gently pipetting it into pre-cold tubes on ice and immediately store the remaining at -20°C.

Note: All cultureware including pipette and centrifuge tubes used should be pre-chilled/ice-cold to avoid the bioGenousTM Organoid Culture ECM from clogging. However, if clogging occurs, the matrix may be re-liquified by placing it at 4°C in ice for 24-48 hours.

4.    bioGenousTM Organoid Culture ECM can be used at a recommended dilution ratio of >70% (ECM: culture medium = 7:3).

Note: Excessive dilution of bioGenousTM Organoid Culture ECM below 50% dilution may result in an extremely thin and fragile non-gelled protein layer that cannot support continuous organoid growth.

5.    Dispense the required volumes of the matrix-cell mixture in the well.

6.    Incubate the plates at 37°C for 15-20 mins and then add the appropriate volume of a pre-warmed growth medium for the specific organoid type.

Directions on Coating with bioGenousTM Organoid Culture ECM

bioGenousTM Organoid Culture ECM (Reduced Growth Factor) could be used in the preparation of thin Gel, thick gel, or thin coating. Thin Gel preparations allow cells to be cultured on top of the gel while the Thick Gel enables the growth of cells within a three-dimensional matrix. Thin Coating could also be done to support cell growth on top of a complex protein layer.

 

Thin Gel
1. Start by thawing the required amount of bioGenousTM Organoid Culture ECM.

2. Gently mix the bioGenousTM Organoid Culture ECM. Be careful not to introduce bubbles into the gel.

3. Dispense 50 μl/cm2 of growth surface into the pre-chilled culture plate.

4. Incubate the plates at 37°C for 30 minutes before use.

5. Aspirate any unbound gel on the surface of the plate and rinse once with the basal organoid medium.

 

Thick Gel

1. Start by thawing the required amount of bioGenousTM Organoid Culture ECM.

2. Gently mix the bioGenousTM Organoid Culture ECM. Be careful not to introduce bubbles into the gel.

3. Add the recommended amount of cells to the bioGenousTM Organoid Culture ECM on ice and dispense 150-200 μl/cm2 of growth surface.

4. Incubate the plates at 37°C for 30 minutes before use.

5. Add culture medium and incubate at 37°C.  

 

Thin Coating Method

1. Start by thawing the required amount of bioGenousTM Organoid Culture ECM.

2. Gently mix the bioGenousTM Organoid Culture ECM. Be careful not to introduce bubbles into the gel.

3. Using the basal organoid medium, dilute the bioGenousTM Organoid Culture ECM. It is necessary to optimize the dilution media to determine the optimal dilution for your investigation.

4. Dispense enough diluted bioGenousTM Organoid Culture ECM to cover the entire growth surface.   

5. Incubate the plates at room temperature for 60 minutes.

6. If any unbound materials remain, aspirate and rinse gently using the basal organoid medium.

 

NB: If gel-coated plates are not used immediately after coating, add PBS to prevent evaporation and store at 4°C for up to 5-10 days.
