Amersham 帶正電荷尼龍膜 Hybond-N+ (30 cm * 3 m)

Amersham 帶正電荷尼龍膜 Hybond-N+ (30 cm * 3 m)

Amersham Hybond-N+ 帶正電荷尼龍膜 0.45um 30cmx3m RPN303B
帶正電荷的尼龍膜與核酸高達(dá)600μg/cm2的結(jié)合能力。建議使用放射性和非放射性的化學(xué)發(fā)光法和chemifluorescence檢測系統(tǒng)。
Amersham公司Hybond™- N +產(chǎn)品在傳統(tǒng)的Southern雜交有著出色的靈敏度。核酸樣品可能是固定的,通過紫外線照射或烘烤,雖然紫外線固定是最好的最大的重復(fù)性。Hybond?N +是不適合堿印跡和固定。

Amersham Hybond-N是一種堅(jiān)固的支撐膜,具有固有的親水性,無需預(yù)潤濕。 紫外光照時(shí)可以快速、輕松地將核酸與尼龍膜交聯(lián)起來。 使用緩沖液體積較少時(shí),建議使用Hybond-NX。

Amersham Hybond™-N+

  • Positively charged nylon membrane with a binding capacity for nucleic acids up to 600 μg/cm2?recommended for use with radioactive or nonradioactive chemiluminescence and chemifluorescence detection systems.
  • Recommended for all high density membrane arrays.

Technical Information

Amersham Hybond™-N+ yields excellent sensitivity in conventional Southern blotting. Nucleic acid samples may be fixed by UV exposure or baking, although UV fixation is best for maximum reproducibility. Hybond-N+ is not suitable for Alkali blotting and fixation.

  • Multiple reprobing is possible without loss of membrane integrity.
  • QC tested in genomic Southern blots using GE Healthcare products.
  • Special sizes available on request.

Human genomic DNA (1, 0.5, 0.125, 0.06 and 0.03 μg loadings) digested with HindIII and transferred to Hybond-N+. Hybridizaton with?A. N-ras, B. p53, and C.?bcl-2 labeled DNA probes and detected using Gene Images™ random-prime labeling with CDP-Star™ detection.

Membranes should be stored at room temperature in a clean dry atmosphere away from excessive heat, light, and noxious fumes. To prevent contamination, handle membranes using gloves or blunt-ended forceps. Hybond-N+ is stable for up to 3 years. Membranes should be kept in the bags in which they are received. Performance is consistent when stored under the recommended conditions.

TECHNICAL SPECIFICATIONS
Pore size 0.45 μm
Nucleic acid size required > 50 bp
