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 temperature was too high the antibody was impure there was one antibody and one antigen there was more than one antigen the temperature was too high the antibody was impure there was one antibody and one antigen 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? The ELISA would develop normally All wells would show uniform over-development due to unbound and excess anti-human Ig enzyme conjugate None of these The ELISA would not develop when the substrate was added The ELISA would develop normally All wells would show uniform over-development due to unbound and excess anti-human Ig enzyme conjugate None of these The ELISA would not develop when the substrate was added ANSWER DOWNLOAD EXAMIANS APP
