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.

Key words: pseudorabies virus (PRV); polyclonal antibody; PK-15 cell
