摘要: 本研究旨在获得抗猪伪狂犬病病毒(PRV)闽A株的多克隆抗体,为PRV的治疗与检测提供理论基础.本研究在PK-15细胞上进行PRV的增殖,测定其TCID50为10-7.372,粗提蛋白后,测定PRV蛋白浓度为3.6 mg/mL.试验选用25只健康、雄性、体重为2.5 kg±0.2 kg的新西兰大白兔为试验动物,用获得的PRV为抗原免疫后,获得抗PRV多克隆抗体.测定其抗血清效价为1:32 000,抗原包被稀释度为1:40,最佳包被条件为4 ℃ 12 h,最佳封闭时间为1 h,酶标二抗最佳工作稀释度为1:8 000.细胞病变中和试验结果表明,本研究制备的PRV抗血清在1:16的稀释情况下能保护50%的PK-15细胞免受PRV的攻击,而阴性血清不能保护PK-15细胞免受PRV的感染.结果表明本研究成功制备了PRV多克隆抗体.

Abstract: This study was aimed to obtain polyclonal antibody against swine pseudorabies virus (PRV) Min A strain,and provide a theoretical basis for the study of the treatment and detection of PRV.This study was performed on PK-15 cell and proliferation of PRV was measured as TCID50 10-7.372,the protein concentration of PRV was measured as 3.6 mg/mL.Choosing five healthy male rabbits (2.5 kg±0.2 kg) as experimental animals and using PRV obtained as the antigen,we got polyclonal antibody against PRV.Antiserum titer was 1:32 000,antigen coating dilution was 1:40,the best coating conditions was 4 ℃ 12 h,the best blocking time was 1 h,the best working dilution of enzyme labled antibody was 1:8 000,the result of cell lesions neutralization test showed that PRV antiserum prepared in this assay at 1:16 dilution could protect 50% of PK-15 cells from being infected by PRV,and negative serum couldn't protect PK-15 cells from being infected by PRV.The study successfully prepared polyclonal antibodies against PRV.
