Description
技术领域
本发明涉及基因工程疫苗技术领域,特别涉及一种I群4型禽腺病毒fiber-2蛋白抗原及其制备基因工程亚单位疫苗的方法和应用。
背景技术
禽腺病毒(fowl adenovirus,FAdV)属于禽腺病毒科禽腺病毒属,禽腺病毒分3个群,I群、Ⅱ群和Ⅲ群。I群禽腺病毒共12个血清型,临床上主要引起包涵体肝炎、心包积液和肌胃糜烂等。Ⅱ群禽腺病毒包括火鸡出血性肠炎病毒(Hemorrhagic enteritis virus,HEV)、大理石脾病毒(Marble spleen disease virus,MSDV)和鸡大脾病毒(Avianadenovirus group II splenomegaly,AASV)。Ⅲ群禽腺病毒主要是禽减蛋综合征病毒(Eggdrop syn-drom virus,EDSV)。FAdV-4型主要引起心包积水肝炎综合征,给国内养鸡业带来严重的经济损失。
禽腺病毒是一种无囊膜的直径粒子为70-90nm的球形颗粒,二十面体对称结构。FAdV的主要结构蛋白有:五邻体(Penton)、六邻体(Hexon)和纤维突起(Fiber)。其中二十面体的12个顶角颗粒为五邻体,240个非顶角颗粒为六邻体以及位于五邻体上的纤维突起,FAdV-4具有2条纤维蛋白。
亚单位疫苗作为一种新型基因工程疫苗,在疾病防控中具有简便、低廉和高效等特点。针对FAdV-4的亚单位疫苗研发中,fiber-2基因由于具有良好的免疫原性,作为疫苗开发的重点。但是fiber-2蛋白由于自身蛋白结构原因,表达后多为包涵体表达,而通过非编码基因调控表达获得针对fiber-2基因的可溶性表达蛋白,对于疫苗的商品化开发和疾病的防控具有重要的意义。
发明内容
本发明为了弥补现有技术的不足,提供了一种工艺简单、安全有效的I群4型禽腺病毒fiber-2蛋白抗原及其制备基因工程亚单位疫苗的方法和应用。
本发明是通过如下技术方案实现的:

(4)用IPTG诱导重组工程菌进行表达、纯化、脱毒后获得fiber-2蛋白,进一步的,该禽腺病毒fiber-2蛋白含量AGP效价≥1:8;
(5)将fiber-2蛋白用PBS稀释,并加入tween-80,制成水相,使用白油、Span-80、硬脂酸铝混合制成油相,将水相、油相混合乳化,得到亚单位疫苗。
本发明在禽腺病毒FAdV-4的fiber-2基因前面添加非编码基因,并将其克隆到原核表达载体pET-28a,转化至大肠杆菌构建工程菌,诱导工程菌表达获得可溶性fiber-2蛋白。其中禽腺病毒fiber-2抗原蛋白的氨基酸序列为SEQ ID NO.2 ,其编码的基因的核苷酸序列为SEQ ID NO.1,并且通过非编码基因调控获得高表达量的可溶性蛋白。
