Figure 3From: The screening and functional study of proteins binding with the BmNPV polyhedrin promoterThe identification of recombinant plasmid pSK-IE- BmRPSA and pSK-IE- dbp . The dbp or BmRPSA gene was inserted into the transient expression vector pSK-IE. Recombinant plasmid pSK-IE-BmRPSA and pSK-IE-dbp were analyzed by PCR and restriction enzyme digestion. M, trans plus II 2000; 1, PCR product of BmRPSA; 2, recombinant plasmid digested with Eco R I, and Xho I; 3, PCR product of dbp; 4, recombinant plasmid digested with Eco R I, and Xho I.Back to article page
