Immunological Techniques What would happen if the anti-human Ig-conjugate is not washed free of the well before the substrate is added? The ELISA would develop normally None of these The ELISA would not develop when the substrate was added All wells would show uniform over-development due to unbound and excess anti-human Ig enzyme conjugate The ELISA would develop normally None of these The ELISA would not develop when the substrate was added All wells would show uniform over-development due to unbound and excess anti-human Ig enzyme conjugate ANSWER DOWNLOAD EXAMIANS APP
Immunological Techniques An antigen preparation and an antibody preparation are tested by immunodiffusion. Three bands are found, indicating that the antibody was impure there was one antibody and one antigen the temperature was too high there was more than one antigen the antibody was impure there was one antibody and one antigen the temperature was too high there was more than one antigen ANSWER DOWNLOAD EXAMIANS APP
