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

Immunological Techniques What would happen if serum is omitted from the ELISA, but all other steps remain same? Both (a) and (b) The OD values would be nearly the same as the assay control Anti-human Ig-conjugate would bind non-specifically to the ELISA plate Anti-human Ig-conjugate would not bind and be washed away Both (a) and (b) The OD values would be nearly the same as the assay control Anti-human Ig-conjugate would bind non-specifically to the ELISA plate Anti-human Ig-conjugate would not bind and be washed away ANSWER DOWNLOAD EXAMIANS APP
