鲤疱疹病毒3型(CyHV-3)又称锦鲤疱疹病毒(KHV),是锦鲤和鲤鱼的致死性病原。本文报道了抗CyHV-3包膜蛋白pORF 132单克隆抗体的制备方法及其应用。构建了3个重组质粒,分别表达1个完整的pORF 132和2个截短的pORF 132。经诱导后,截短的pORF 132以可溶性形式成功表达,纯化的重组蛋白用于制备单克隆抗体。获得两个杂交瘤细胞克隆,4 E11和4 B11,mAb 4 E11与CyHV-3感染的细胞反应,而不与CyHV-2(金鱼造血坏死病毒)和IcHV-1(癍点叉尾鱼病毒)感染的细胞反应。初步建立了单克隆抗体4 E11与抗CyHV-3 IgY的抗原捕获ELISA方法。该抗原捕获ELISA可区分CyHV-3感染和未感染的鱼样品
Cyprinid herpesvirus 3 (CyHV-3), also named koi herpesvirus (KHV), is a lethal pathogen of koi and common carp Cyprinus carpio. In the present study, we described a procedure to generate.monoclonal antibodies (mAbs) against the envelope protein pORF132 of CyHV-3 and application of the mAb. Three recombinant plasmids targeting the expression of one complete pORF132 and two truncated pORF132 were constructed, respectively. After induction, a truncated pORF132 was successfully expressed in a soluble form and the purified recombinant protein was used in the preparation of mAbs. Two hybridoma cell clones, 4E11 and 4B11, were obtained and mAb 4E11 reacted to CyHV-3 infected cells and not to CyHV-2 (goldfish hematopoietic necrosis virus) and IcHV-1(channel catfish virus) infected cells. An antigen-capture ELISA based on the pair of mAb 4E11 and anti-CyHV-3 IgY was primarily constructed. This antigen-capture ELISA could distinguish between the CyHV-3 infected and uninfected fish samples
