Description
This Human gp120 recombinant protein spans the amino acid sequence from region 33-511aa. The calculated molecular weight for this env protein is 69.7 kDa. This env protein is produced using e.coli expression system. The N-terminal 6xHis-SUMO tag was smoothly integrated into the coding gene of env, which enables a simple process of detecting and purifying the env recombinant protein in the following steps
