Figure 3: Gene fragment of PEGase1 amplified from the plasmid of E. coli transformant, and from the genomic DNA mold recombinants by PCR. Lane M: the standard molecular weight DNA marker. Lanes 1: the gene fragment (930 bp) of PEGase1 cloned from the plasmid of E. coli transformant (A), and from the genomic DNA of mold recombinants (B), respectively.
