查询词典 amplification factor

With genomic DNA of Clostridium stercorarium as a template, a structural gene pel9A encoding pectate lyase was obtained by PCR amplification. The pel9A was cloned into pET28a to recombine an express plasmid pPel9A, and then the plasmid pPel9A was transformed into E. coli BL-21, expressed under the control of T7lac promoter at 37℃.
