Name the other ion formed when ammonia dissolves in water Give one test that can be used to detect the presence of the ion produced .

A: ELISA can enable very easy detectron of infection through antigen antibody interaction. R : It is a nucleic acid based diagonostic tool that can confirm presence of infectious microbe at early stages.

Name the following. The device which detects the presence and direction of electric current

Infection by a pathogen can be detected by the presence of antigens or by detecting the antibody synthesized against the pathogen. The test/s based on this principle is/are

Assertion: ELISA is based on the principle of antigen antibody interaction Reason :Infection by pathogen can be detected by the presence of antigens or by detecting antibodies synthesized against the pathogen

Assertion : ELISA test is based on antigen-antibody interactions where a pathogen can be detected by the presence of antibodies (proteins,glycoproteins, etc) on it Reason : The pathogen antibody to be identified is immobilised on the surface of specially constructed ELISA plates and is then tested.
