ABSTRACT
OBJECTIVE To recombine J chain gene with HNP-1 into a new germicidal(molecule) J-HNP-1,which can connect with pIgR by J chain,so that by using pIgR as a "bridge" the J-HNP-1(germicidal) peptide can be transported into the epithelial cell of mucous membrane to kill the intracellular microorganisms,then the recombinant is inserted into the mammalian expression system.METHODS The J chain and HNP-1 cDNA were amplified from the plasmids respectively by PCR,then the two cDNA fragments were recombined into J-HNP-1 by recombinant PCR.The J-HNP-1 cDNA fragment was inserted into the(mammalian) expression vector pcDNA3.1(-)/Myc-HisC.RESULTS The J-HNP-1 recombinant was obtained by(connection) of J chain and HNP-1 cDNA by PCR.The recombinant J-HNP-1 cDNA was 786bp.CONCLUSIONS The recombinant J-HNP-1 cDNA and the construction of expression vector are the basis for the new bactericidal peptide production.
