Recombinant FnCpf1 production, purification, and SDS-PAGE analysis

The backbone for BBa_K3521005 was derived from pET-28a vector. The recombinant plasmid was transformed into BL21 (DE3) competent cells and induced with IPTG. After induction, a specific protein band that is consistent with the theoretical molecular weight of FnCpf1 was detected in SDS-PAGE (Figure 2). The recombinant FnCpf1 was successfully purified by Ni-affinity chromatography.

The resulting supernatants were loaded to the PAGE gel with different amounts. Lane2 1-4: the samples from the cultures induced with 1 mM IPTG; Lane2 5-8: the samples from the cultures induced with 0.5 IPTG; lane 9: protein molecular weight standards.
