摘要: 本研究旨在利用基因工程的方法,制备犬瘟热(canine distemper,CD)疾病诊断用抗原。提取犬瘟热病毒基因组,RT-PCR扩增犬瘟热病毒(canine distemper virus,CDV)F1基因序列,克隆并测序。将F1基因定向克隆到原核表达载体pET28a多克隆位点,阳性重组质粒转化到大肠杆菌BL21(DE3)中,IPTG诱导表达。SDS-PAGE和Western blotting鉴定表达产物,并用Ni柱亲和层析纯化目的蛋白。结果显示表达的F1重组蛋白能与犬瘟热标准阳性血清发生反应,具有良好的反应原性,可以作为犬瘟热疾病的诊断用抗原。

Abstract: To prepare CDV antigen for diagnosis, gene engeneering method was explored. CDV genome was extracted, F1 gene was amplified by RT-PCR cloned and then sequenced. The F1 gene was cloned into expression plasmid pET28a and expressed by the induction of IPTG inducer. The recombined protein was examined by SDS-PAGE and Western blotting,purified by Ni column. The results indicated the recombined protein could react with CDV positive serum and might be used as CDV diagnostic antigen.

Key words: canine distemper virus; F1 gene; expression
