Standardization of an Enzyme-Linked Immunosorbent Assay for Detection of Infectious Bronchitis Virus Antibody.

Authors

Abstract

An indirect enzyme–linked immunosorbent assay (ELISA) was developed for screening of antibody to avian infectious bronchitis virus (IBV). Antigen was prepared from whole-purified IBV Massachusetts serotype (BR 801 strain). Optimum dilution with minimum background for antigen concentration, rabbit anti-chicken conjugate and sera in developed ELISA was determined 0.1μg/ml, 1:3000 and 1:100, respectively. The optical densities (OD) were compared with a commercial ELISA kit. Also, the results of ELISA were compared to hemagglutination inhibition (HI) test. The correlation coefficient of the results of both ELISAs and HI was significant (P
