          產(chǎn)品簡介

           

          白細(xì)胞介素-3Interleukin-3,IL-3是一種造血生長因子,可促進(jìn)巨核細(xì)胞、粒細(xì)胞-巨噬細(xì)胞、紅系、嗜酸性粒細(xì)胞、嗜堿性粒細(xì)胞和肥大細(xì)胞譜系的定向祖細(xì)胞的存活、分化和增殖。IL-3由T細(xì)胞、肥大細(xì)胞和嗜酸性粒細(xì)胞產(chǎn)生,可增強(qiáng)血小板生成素、吞噬作用和抗體介導(dǎo)的細(xì)胞毒性。其激活單核細(xì)胞的能力表明IL-3可能具有額外的免疫調(diào)節(jié)作用。許多IL-3活性依賴于與其他細(xì)胞因子的共同刺激。

          重組人IL-3是一種15.0kDa的重組蛋白,含有133個(gè)氨基酸殘基。本品由大腸桿菌表達(dá),以凍干粉形式提供,高活性、高純度、低內(nèi)毒素、無標(biāo)簽。
