Immunological Techniques An antigen preparation and an antibody preparation are tested by immunodiffusion. Three bands are found, indicating that 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 the antibody was impure there was one antibody and one antigen the temperature was too high 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 None of these The ELISA would develop normally 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 None of these The ELISA would develop normally The ELISA would not develop when the substrate was added ANSWER DOWNLOAD EXAMIANS APP
