Objective To construct mellitin gene expression clone. Methods Two fragments of manmade oligonucleotide,A and B, were made into target gene by Klenow enzyme . Then ,the target gene and prokaryotic expression vector Pmal-p2 were restricted simultaneously and ligated by T4 DNA ligase. The recombinant plasmid was transformed into E.coli. DH5α. depending on the signs of α-complementary. We selected the positive clone and it was confirmed by restriction enzyme and DNA sequencing. Results The positive clone was identified with recombinant mellitin gene clone. Conclusion The construction of recombinant mellitin gene expression clone is the basis of mellitin protein expression and activity identification .
