Cloning and Prokaryotic Expression of the VP1 Gene of Pancreotropic Duck Hepatitis Type 1 Virus

The structure protein (VP1) gene of pancreotropic duck hepatitis type 1virus MPZJ1206 strain was amplified by RT-PCR and integrated into the prokaryotic expression vector pGEX-6P-1, then expressed in E.coli.The SDS-PAGE results of the expressed protein demonstrated that the expression of recombinant VP1 protein of 52 kDa was in a high level, which laid a good foundation for the molecular diagnosis development and the function research of the VP1 protein.
