Rat CNTF / Ciliary Neurotrophi

分子别名（Synonym）:CNTF 种属（Species）：Rat 表达系统（Expressed Host）：E. coli 制剂（Buffer）：Lyophilized from sterile 50mM Tris, 0.1M NaCl, pH 7.5 分子量（Molecule Mass）：The recombinant rat CNTF consisting of 200 amino acids and has a calculated molecular mass of 22.9 kDa. It migrates as an approximately 24 kDa band in SDS-PAGE under reducing conditions. 内毒素（Endotoxin）：＜1.0 EU per μg by the LAL method. 生物活性(Activity)：1. Measured by its binding ability in a functional ELISA. Immobilized rat CNTF (Cat:R1236-NAE) at 10 μg/ml (100 μl/well) can bind biotinylated rat CNTFR-His (aa 1-346) (Cat:B) with a linear range of 1.56-50.0 ng/ml. 表达区间（Protein Construction）：A DNA sequence encoding the rat CNTF (P20294) (Ser 2-Met 200) was expressed and purified. 存储条件（Storage）： For long term storage, the product should be stored at lyophilized state at -20℃ or lower.Please avoid repeated freeze-thaw cycles. No activity loss is observed after storage at:4-8℃ for 12 months in lyophilized state;-70℃ for 3 months under sterile conditions after reconstitution. 运输条件： In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
