Interferon alpha 2b, IFNA, INFA2, MGC125764, MGC125765.

IFN-alpha is produced by macrophages and has antiviral activities. Interferon stimulates the production of two enzymes: protein kinase and an oligoadenylate synthetase.

IFN-α 由巨噬细胞产生并具有抗病毒活性。 干扰素刺激两种酶的产生：蛋白激酶和寡腺苷酸合成酶。

Interferon-a 2b Human Recombinant produced in E.coli is a single, non-glycosylated, polypeptide chain containing 165 amino acids and having a molecular mass of 19269 Dalton. The Pegylated IFN-a 2b is produced by attaching a 20kDa mPEG-aldehyde to the N-terminal IFN alpha-2b.
Interferon-a 2b is purified by proprietary chromatographic techniques.

在大肠杆菌中产生的干扰素-a 2b 人重组体是单一的、非糖基化的多肽链，含有 165 个氨基酸，分子量为 19269 道尔顿。 聚乙二醇化 IFN-a 2b 是通过将 20kDa mPEG-醛连接到 N 端 IFN alpha-2b 上产生的。
干扰素-a 2b 通过专有的色谱技术进行纯化。
