GST-β-catenin-His双标签融合蛋白的原核表达、纯化及鉴定
Prokaryotic expression, purification, and identification of GST-β-catenin-His double labeled fusion protein
摘要
Abstract
The cDNA sequence of p-catenin was amplified through RT-PCR with 6xHis tag added in the gene downstream, cloned into the vector pGEX-4T-l. The plasmid transformed into BL21pLysS was induced by IPTG. The induced fusion protein was purified stepwise using Glutathione Sepharose 4B and Ni columns. The final protein ran on SDS-PAGE with a specific band at the expected size of 114 kDa. Western Blotting showed that the purified protein can be recognized by the anti-β-catenin, anti-GST, and anti-His antibodies, respectively. All these results provide a basis for further study of p-catenin function.关键词
