WebThe coding region for the sortase A (SrtA) of Staphylococcus aureus was fused at the N-terminus of LfcinB. The SrtA-LfcinB fusion protein in E. coli C43(DE3) was expressed with the expected sizes of 21 kDa and 38 kDa by pET21b-SrtA-LfcinB and pET32-1SrtA-LfcinB constructs, respectively. Increased levels of the TrxA-His-SrtA-SrtA-LfcinB fusion protein … WebUsing sterile technique, add IPTG to a final concentration of 0.2-1.0 mM, to induce overexpression. Incubate with shaking (250 rpm) for 6 hr to overnight. Remove 1 ml aloquots at appropriate 1-2 hour intervals, spin down and store cell pellets frozen.
