摘要
Abstract
Based on the group Ⅰ fowl adenovirus serotype 4 (FADV-4) genome sequence,a pair of specific primers were designed to amplify the hexon gene by PCR,and then cloned into the pET-28a vector named pET-28a-Hexon.The recombinant plasmid was transformed into competent cells BL21 induced with IPTG for expression.The results showed that 49 ku of the fusion proteins was obtained following an SDS-PAGE analysis.Expressions induced with different IPTG concentrations,temperatures and durations suggested the best IPTG induction concentration to be 1 mmol/L,the optimum temperature to be 37℃,and the optimal duration of time to be 4 h.Western-bolt analysis showed that the recombinant fusion proteins reacted specifically with the FAdV-4 positive serum.The purified recombinant proteins were inoculated in BALB/c mice to prepare polyclonal antibody against hexon protein.The titer of the polyclonal antibody was found to be higher than 1 ∶ 64 000,assayed by indirect ELISA.The high efficiency single factor serum prepared in this experiment laid the foundation for the study on the specific detection of serotype 4 adenovirus.关键词
