OmpA-HIV protease site-SH3



Usage and Biology

T7 promoter driven OmpA-HIV protease site-SH3 fusion protein expression cassette.

This part is used for binding to target protein with multi-proline sequence. The target protein can then be efficiently released by HIV protease.

DAPI Thuexp bind p d.png Thuexp bind n d.png
merge Thuexp bind p m.png Thuexp bind n m.png

The remaining were mixed with E. coli expressing OmpA-HIV protease at room temperature for 30 minutes to release the cargo.

After washing with distilled water twice, bacteria were fixed on a slip and stained with DAPI.
