Abstract: The mature peptide sequence of rabbit defensin NP-1 gene was modified with favour codes for E.coli and synthesized chemically.The target gene fragment modified was cloned into vector T-easy,and then inserted into fusion expression plasmid pMAL-p2X through digesting of two restriction enzymes.The positive recombinant expression vector pMAL-NP-1 was transformed into E.coli TB1,which could effectively produce the fusion protein MBP and NP-1 induced with IPTG.
