GENERATION AND CHARACTERIZATION OF MONOCLONAL ANTIBODIES AGAINST GE PROTEIN OF PSEUDORABIES VIRUS VARIANT STRAIN
摘要
Abstract
The gene encoding the key antigenic epitope regions of gE of pseudorabies virus (PRV) was amplifi ed in PCR and inserted into the pCold-TF expression vector. Expression of the recombinant fusion protein about 90 kDa was observed under 1mmol/L IPTG environment. The recombinant gE protein purified with nickel ion metal affinity chromatography was used to immunize 6-week-old BALB/c female mice for the preparation of monoclonal antibodies (McAbs). Two hybridoma cell lines (5B2 and 6E6) were obtained for stably producing anti-gE protein McAb. These two McAbs reacted with PRV variant strain (JS-2012) but not with the gE deleted vaccine virus Bartha-K61 strain in indirect immunofl uorescence assay(IFA). Western blot results showed that 5B2 and 6E6 did not react with PRV(JS-2012). The results indicated that 5B2 and 6E6 might be against confomational epitope of gE. These specifi c monoclonal antibodies might provide a good tool for the development of PRV diagnostic method.关键词
