Abstract: A double-antibody sandwich ELISA (DAS-ELISA) was developed for the detection of subgroup J avian leukosis virus (ALV-J). Antibodies of DAS-ELISA were purified from the ALV-J gp85 mono-specific serum prepared by our laboratory earlier. Results of statistics analyses showed that DAS-ELISA had good specificity, repeatability and stability. The limitation of viral antigens for detection was 0.165 μg/mL. The coincidence between PCR and DAS-ELISA established here was 85.2%.

Key words: avian leukosis; subgroup J avian leukosis virus(ALV-J); double-antibody sandwich ELISA(DAS-ELISA)
