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 more than one antigen there was one antibody and one antigen the temperature was too high the antibody was impure there was more than one antigen there was one antibody and one antigen 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) Anti-human Ig-conjugate would bind non-specifically to the ELISA plate The OD values would be nearly the same as the assay control Anti-human Ig-conjugate would not bind and be washed away Both (a) and (b) Anti-human Ig-conjugate would bind non-specifically to the ELISA plate The OD values would be nearly the same as the assay control Anti-human Ig-conjugate would not bind and be washed away ANSWER DOWNLOAD EXAMIANS APP
Immunological Techniques In Counter immunoelectrophoresis electrophoresis will drive the antibody and antigen parallel to each other the antibody will migrate towards anode the antibody will migrate towards cathode electrophoresis will drive the antibody and antigen toward each other electrophoresis will drive the antibody and antigen parallel to each other the antibody will migrate towards anode the antibody will migrate towards cathode electrophoresis will drive the antibody and antigen toward each other ANSWER DOWNLOAD EXAMIANS APP
