Expression and purification of TAT-HBX-EGFP fusion protein and its transmembrane distribution in mouse / 中华实验和临床病毒学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To highly express TAT-HBX-EGFP fusion protein and study its distribution in mouse liver.</p><p><b>METHODS</b>TAT-HBX-EGFP recombinant vector was constructed and fusion protein was induced by IPTG and expression in BL21; fusion protein was purified by Ni-NTA argarose, then injected into the peritoneal cavity of the mice. Distribution of fusion protein was observed by immunofluorescence.</p><p><b>RESULTS</b>TAT-HBX-EGFP was highly expression in E. coli; HBX could be induced into mouse liver by TAT.</p><p><b>CONCLUSION</b>HBX protein could be induced into mouse liver by TAT induced peptide.</p>
