摘要: 试验克隆获得了猪全长CD150基因序列,将其连接到真核表达载体pEGFP-N1上获得重组载体pEGFP-N1-CD150。通过测序、Western-blot、瞬时转染,确认了pEGFP-N1-CD150的表达效果。结果表明,pEGFP-N1-CD150载体测序结果与CD150基因序列比对率100%;Marc-145细胞密度在70%~80%时质粒转染效果最佳,24 h为转染高峰期,绿色荧光最强;Western-blot鉴定到分子质量约为80 kDa的蛋白,与预期大小符合,表明CD150蛋白成功表达。

Abstract: The full-length porcine CD150 gene sequence was cloned and connected to the eukaryotic expression vector pEGFP-N1 to obtain the recombinant vector pEGFP-N1-CD150. The expression of pEGFP-N1-CD150 was confirmed by sequencing, Western blot and transient transfection. The results showed that the sequence comparison rate of pEGFP-N1-CD150 vector and CD150 gene sequence was 100%; when the density of Marc-145 cells was 70%~80%, the transfection peak was 24 h, and the green fluorescence was the strongest; the protein with molecular weight of about 80 kDa was identified by Western blot, which was consistent with the expected size, indicating that CD150 protein was successfully expressed.

Key words: porcine, CD150, eukaryotic expression
