The SDS-PAGE analysis of recombinant p24 protein. Lane M, Protein molecular marker; Lane 1, E.coli BL21(DE3) whole cell harboring pQE30-p24 after induction with IPTG (about 24 kDa); Lane 2, E. coli BL21(DE3) whole cell harboring pQE30-p24 before induction with IPTG; Lane 3, host cell E. coli BL21(DE3) (as negative control); Lane 4, E.coli whole cell harboring empty plasmid pQE30 after induction with IPTG.
