Write answer in between .Q:A graduate student is developing the research design for a current project on the detection of ovarian tumor markers in mice. The main method requires the use of chromogenic substrates, in which a reaction may be interpreted according to an enzyme-mediated color change. The detection of which of the substances below is routinely used in clinical practice and applies the above-described method?? A: ABO blood types, B: Anti-D antibodies, C: P24 antigen, D: Epstein-Barr virus infection, E: Antibodies in autoimmune hemolytic anemia,  <response>: This is a question about detecting substances in clinical practice using chromogenic substrates and enzyme-mediated color change. The key points are:- The method involves using chromogenic substrates and interpreting color change mediated by enzymes.- The substance needs to be one that is routinely detected in clinical practice using this method.Going through the choices:A ABO blood types are detected by agglutination reactions, not chromogenic substrates.B Anti-D antibodies are detected by agglutination reactions, not chromogenic substrates.C P24 antigen is detected for HIV infection, but not routinely in most clinical settings. D Epstein-Barr virus infection is usually detected by serology, not chromogenic substrates.E Antibodies in autoimmune hemolytic anemia are detected by agglutination reactions, not chromogenic substrates.C: P24 antigen
