Coomassie blue-stained SDS-PAGE of soluble GST-B7-2-PhaP fusion protein. Lane 1: the soluble fraction was recovered after centrifugation of whole crude lysate of E. coli BL21 (DE3) transformed with pGEX-B72P plasmid. Lane 2: purified soluble GST-B7-2-PhaP fusion protein. Protein weight marker (Institute of Biochemistry and Cell Biology, SIBS, CAS, China) was loaded in lane M.
