ABSTRACT
The major antigen region of E2 gene of Hog Cholera Prevalent Strain (Guangxi Yuling Strain) and Chinese Hog Cholera Lapinised Virus (C-strain) derived from hog and rabbit spleen tissue, was amplified by reverse transcription polymerase chain reaction(RT-PCR) and the nested Polymerase Chain Reaction (nPCR). After the amplified fragments were cloned into the expression vector pPROEX-HTb, the recombinant plasmids pPROEX-GXYL and pPROEX-C were obtained. The insert position, the size and the reading frame were right by PCR, restriction digestion and the sequence analysis. SDS-PAGE indicated that both of the reciepient germs transducted and induced by the recombinant plasmids pPROEX-GXYL and pPROEX-C could express the major antigen region of E2 gene. Western-blot indicated that the expressed antigen protein could be recognized by the positive serum of CSFV.
