产品名称：Recombinant Human IFN-alpha-2B Protein

规格或纯度：无动物源, Carrier Free, 生物活性, ActiBioPure™, ≥98%(SDS-PAGE&HPLC)

产品介绍：

干扰素（IFN）以其在宿主防御机制中的关键作用而闻名。Ⅰ型干扰素包括IFN-alpha 家族，IFN-beta， -omega，-kappa 和 Limitin/IFN-zeta，对调节病毒感染的免疫应答具有重要意义。Ⅱ型干扰素组仅包括干扰素γ。IFN-γ是一种多功能细胞因子，具有抗增殖、免疫调节和促炎症作用，对免疫应答的许多方面都很重要。Ⅲ型干扰素家族包括IL-29/IFN-lambda 1， IL-28A/IFN-lambda 2， IL-28B/IFN-lambda 3， and IFN-lambda 4。与Ⅰ型干扰素类似，Ⅲ型干扰素具有抗病毒、抗增殖和免疫调节作用。
