Comparative Study on the Indirect ELISA Methods Based on the Different Recombinant Proteins of Rabies Virus
摘要
Abstract
This study was designed to compare the indirect ELISA methods for detection of dog antibodies against rabies virus based on the recombinant matrix protein (M) and phosphoprotein (P). The M gene of rabies virus LEP-Flury strain was amplified by PCR and cloned into prokary-otic expression vector pGEX-6P-l. The resultant constructed pGEX-RV-M plasmid was transformed into BL21 (DE3) and protein expression was analyzed by SDS-PAGE and Western blot. The results of SDS-PAGE showed that the M protein was efficiently expressed, which were mainly soluble, and purified with the affinity chromatography. The results of Western blot indicated that the recombinant protein M showed good immunogenicity. The indirect ELISA methodwas established with the purified recombinant protein M, and a total of 95 serum samples were detected by the method and the indirect ELISA method based on the recombinant protein P respectively. The results showed that compared with the commercially available ELISA kit coating RV as antigen, the indirect ELISA method based on recombinant protein P had a higher coincidence rate, and it can replace the ELISA method based on RV.关键词
