Human β-NGF / Beta-NGF Protein

分子别名（Synonym）:Beta-NGF,HSAN5,NGFB 种属（Species）：Human 表达系统（Expressed Host）：CHO Stable Cells 制剂（Buffer）：Lyophilized from sterile 20mM NaAc, 150mM NaCl, pH 5.5 分子量（Molecule Mass）：The mature recombinant human β-NGF consists of 118 amino acids and has a predicted molecular mass of 13.2 kDa. β-NGF exists as a non-disulfide linked homodimer in solution. 内毒素（Endotoxin）：＜1.0 EU per μg by the LAL method. 生物活性(Activity)：Measured in a cell proliferation assay using TF-1 human erythroleukemic cells. 表达区间（Protein Construction）：A DNA sequence encoding the mature form of human β-NGF (NP_002497.2) (Ser 122-Arg 239) was expressed. 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.
