摘要: 从经PMA刺激的小鼠脾细胞中提取总RNA, 采用RT-PCR技术获得鼠白细胞介素15(mIL-15)基因, 将其克隆至真核表达质粒VR1012中, 转染COS-7细胞, 将转染细胞裂解, Western blot检测. 表明获得了mIL-15真核表达载体, 其具有完整的带有信号肽的mIL-15序列, 重组结果正确, Western blot检测阳性. 并获得有生物活性的mIL-15蛋白.

Abstract: Murine splenocyte was harvested after the mouse was stimulated by PMA, the cells were extracted for total RNA and RT-PCR, and IL-15 eukaryotic express plasmid was then constructed. COS-7 cell line was transfected by this plasmid, supernatant and the cells were harvested. The supernatant was serially by diluted to detect the bioactivity and express level by western blot. This recombinant murine IL-15 eukaryotic plasmid can increase immune response as DNA vaccine adjuvant potentially.

Key words: mIL-15, clone, biological activity assay
