產(chǎn)品詳情介紹
白介素-2（Interleukin-2，IL-2）是第一個被克隆的白介素因子，又稱T細(xì)胞生長因子，與IL-2受體（IL-2R）結(jié)合可刺激T細(xì)胞進(jìn)入細(xì)胞分裂周期，使T細(xì)胞在體外長期存活[1]。除T細(xì)胞外，IL-2也可通過與NK細(xì)胞表面的IL-2R結(jié)合促進(jìn)NK細(xì)胞的增殖和殺傷活性[2]。IL-2是一個多效性細(xì)胞因子，還可以促進(jìn)腫瘤浸潤淋巴細(xì)胞的增殖、促進(jìn)B細(xì)胞增殖和產(chǎn)生免疫球蛋白、刺激巨噬細(xì)胞提高其吞噬能力[3]。
本產(chǎn)品由134個氨基酸殘基組成，由CHO細(xì)胞表達(dá)，經(jīng)分離和高度純化后凍干制成。
