Immunological Techniques An antigen preparation and an antibody preparation are tested by immunodiffusion. Three bands are found, indicating that 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 there was more than one antigen ANSWER DOWNLOAD EXAMIANS APP
