Usage and Biology

Plasmid construction

We placed 6×His tag into plasmid PET-28a for protein isolation and purification and tranformed PET-28a-6×His-CsnBP115A into E. coli BL21 (DE3).

SDS-PAGE analysis of 6×His-CsnB-P115A

The purification of the CsnB-P115A enzyme was accomplished using Ni-NTA affinity chromatography, which facilitated the isolation of the target protein due to the presence of a 6×His tag. The effectiveness of the purification process was confirmed by SDS-PAGE analysis of both the unpurified and purified protein samples. As depicted in the figure below, a specific lane 3 corresponding to the mutant enzyme was observed at approximately 30 kDa in the unpurified sample, consistent with the expected molecular weight. After purification, the mutant enzyme demonstrated a profile reminiscent of the wild-type CsnB, displaying a single band at the same molecular weight as the unpurified enzyme solution.
