PlacIq_lacI_Ptac driven PhoA-CaAP
To test the secretion efficiency of our 5 secretion peptides fused CaAP(Calcium Absorption Peptide) guided by 5 secretion peptides, we put them under the regulation of the iPTG inducible promoter, Ptac, and expressed them in E.coli. BL21 strain respectively. Thus, quantified characterization of these secretion peptides fused with CaAP is expected to be achieved through the different quantity of the target protein, namely CaAP, in the bacterial lysate and the culture medium.

Characterization
We have successfully cloned NSP4/PhoA/OmpA guided CaAP(Calcium Absorption Peptide) under the regulation of the iPTG inducible promoter, Ptac, and expressed it in E.coli.BL21. As shown in the figure below,PhoA can guide CaAP to secrete into the extracellular space.
