Applications of BBa_K533002

This part is used for specific binding to proteins with multi-proline peptide in the media and then releasing the cargo after interaction with HIV protease.

E. coli with the plasmid for OmpA-HIV site-SH3 is induced with 0.1mM IPTG at 18 centigrade for 12 hours before harvesting by mild centrifuge.

E. coli expressing OmpA-HIV protease site-SH3 was mixed with mCherry solution at room temperature for 30 minutes.

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

Color Channel E. coli with IPTG induction E. coli without induction
mCherry Thuexp bind p.png Thuexp bind n.png
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.
