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.

Figure 2. SDS-PAGE analysis of FnCpf1 production in BL21 (DE3) cells. After induction, cells were collected by centrifugation and broken by sonication. 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.
