Immunological Techniques What would happen if serum is omitted from the ELISA, but all other steps remain same? Anti-human Ig-conjugate would bind non-specifically to the ELISA plate The OD values would be nearly the same as the assay control Both (a) and (b) Anti-human Ig-conjugate would not bind and be washed away Anti-human Ig-conjugate would bind non-specifically to the ELISA plate The OD values would be nearly the same as the assay control Both (a) and (b) Anti-human Ig-conjugate would not bind and be washed away ANSWER DOWNLOAD EXAMIANS APP
