ProSpec-IFN a 2b Human, Yeast/CYT-460

Interferon alpha 2b, IFNA, INFA2, IFN-? 2b, 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-alpha 2b Human Recombinant produced in yeast is a single, glycosylated, polypeptide chain containing 165 amino acids and having a molecular mass of approximately 19 kDa.
The Interferon-alpha 2b gene was obtained from human leukocytes.
The IFN-a 2b is purified by proprietary chromatographic techniques.

酵母中产生的干扰素-α 2b 人重组体是单条糖基化多肽链，含有 165 个氨基酸，分子量约为 19 kDa。
干扰素-α 2b 基因是从人类白细胞中获得的。
IFN-a 2b 通过专有色谱技术进行纯化。

Saccharomyces cerevisiae.

Sterile Filtered White lyophilized powder.

Lyophilized from a 0.2μm filtered concentrated solution in PBS, pH-7.4.

It is recommended to reconstitute the lyophilized glycosilated IFN alpha 2b in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

建议在不低于 100µg/ml 的无菌 18MΩ-cm H2O 中重构冻干的糖基化 IFN α2b，然后可以进一步稀释成其他水溶液。

Lyophilized glycosilated IFN-a 2b although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IFN-alpha 2b should be stored at 4°C between 2-7 days and for future use below -18°C.
For long term storage it is recommended to add a carrier protein .
Please prevent freeze-thaw cycles.

冻干的糖基化 IFN-a 2b 虽然在室温下可稳定保存 3 周，但应在 -18°C 以下干燥储存。 重构后，IFN-α 2b 应在 4°C 下储存 2-7 天，以备将来在低于 -18°C 的温度下使用。
对于长期储存，建议添加载体蛋白。
请防止冻融循环。

Greater than 98.0% as determined by Analysis by RP-HPLC.
Analysis by -PAGE.

The sequence of the first five N-terminal amino acids was determined and was found to be Cys-Asp-Leu-Pro-Gln.

确定了前五个 N 端氨基酸的序列，发现是 Cys-Asp-Leu-Pro-Gln。

The specific activity as determined in a viral resistance assay was found to be no less than 300,000,000IU/mg.
