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 Both (a) and (b) The OD values would be nearly the same as the assay control Anti-human Ig-conjugate would not bind and be washed away Anti-human Ig-conjugate would bind non-specifically to the ELISA plate Both (a) and (b) The OD values would be nearly the same as the assay control Anti-human Ig-conjugate would not bind and be washed away ANSWER DOWNLOAD EXAMIANS APP
Immunological Techniques What would happen if the anti-human Ig-conjugate is not washed free of the well before the substrate is added? All wells would show uniform over-development due to unbound and excess anti-human Ig enzyme conjugate The ELISA would not develop when the substrate was added None of these The ELISA would develop normally All wells would show uniform over-development due to unbound and excess anti-human Ig enzyme conjugate The ELISA would not develop when the substrate was added None of these The ELISA would develop normally ANSWER DOWNLOAD EXAMIANS APP
