title: A sandwich ELISA for bovine serum in viral vaccines.
abstract: A double antibody sandwich ELISA for the detection of bovine serum in viral vaccines was developed and standardized with commercially available reagents. The detection limit by ELISA was 0.5 ng ml-1. ELISA was found to be 50-400 times more sensitive than the currently used assays. It was concluded that ELISA is a specific, sensitive and reproducible method for the determination of residual amounts of bovine serum in viral vaccines.
