草莓镶脉病毒外壳蛋白的原核表达及多抗血清制备
Prokaryotic expression and antiserum preparation of coat protein of Strawberry vein banding virus
摘要
Abstract
The coat protein gene (cp) of Strawberry vein banding virus (SVBV ) was amplified by PCR. SVBV cp gene was ligated to the prokaryotic expression vector pET-32a,and the recombinant plasmid was transformed into Escherichia coli BL21 ( DE3 ). BL21 was induced by IPTG with a final concentration of 0.05 mmol·L-1 to express fusion protein. It was indicated that SVBV cp gene gained fusion expression by SDS-PAGE and Western-blot analysis. The recombinant fusion protein was purified with Ni2+-NTA resin,and the polyclonal antiserum was obtained by immunizing rabbit. Dot-ELISA detection method was established by utilizing the polyclonal antiserum. The detection result showed that the acquired specifically polyclonal antiserum could be used for quick detection of strawberry infected with SVBV.关键词
