p’BCPB+ plasmid restriction analysis. Recombinant plasmids were analyzed by restriction digestion. M is molecular DNA ladder. 5113, 5156, 1015 and 2015 stands for the four recombinant plasmids derived from backbone pBCPB+. For each plasmid, the first lane shows undigested DNA and the second lane shows the restricted DNA.
