摘要
从ConA活化的昆明小鼠脾细胞中提取总RNA,利用RT-PCR方法扩增得到小鼠的IL-10基因。编码序列经测序验证后,将其克隆入表达载体pET-28a,构建IL-10基因的重组原核表达载体,在大肠杆菌(DE3)中诱导表达目的蛋白。SDS-PAGE结果表明,该表达产物的分子量与预期值相符,Western blot结果说明小鼠IL-10基因得到了表达。
The total RNA was extracted from spleen cells of Kunming mouse stimulated by ConA. IL-10 gene of the mouse was amplified by reverse transcription-polymerase chain reaction (RT- PCR). Coding sequence which was identified by DNA sequencing was cloned into the expression vector PET-28a to construct prokaryotic expression vector. The recombinant protein was expressed in B121 (DE3). The result of SDS - PAGE showed that the molecular weight of the expressed product was identical to that of prediction. The result of Westernblot demonstrated that the expressed product had reactiongenicity.
