To optimize enzyme linked immunosorbent assays (ELISAs) for the detection of virus-specific antibodies, a range of commercially available microtitre plates was evaluated for their ability to bind virus antigen. Rinderpest virus and foot-and-mouth disease virus were investigated as target antigens. Binding capacity for antigen, binding ratios (attachment of specific antibody versus that of non-immune antibody) and the variation in the results of the tests within and between plates were measured. Binding capacity was found to be greater with rinderpest virus (RPV) antigen than with foot-and-mouth disease virus (FMDV) antigen, although higher binding ratios were obtained with FMDV antigen. Variation within and between plates was generally less with RPV antigen than with FMDV antigen. One plate could not be said to out-perform the other plates in all tests. For our purpose, that is the detection of monoclonal antibody production against a variety of virus antigens, a number of plates were found to be suitable (e.g. Dynatech M129B, Flow 77-172-05 and Nunc 4-39454). The differences in the performances of the microtitre plates with these two virus antigens highlights the need for consideration of the solid phase as part of the standardization procedures for ELISAs.
