Principle of CAPS and dCAPS Markers

Types of ELISA-Plate on the basis of binding structure between antibody and antigen: 1- Direct ELISA (Involve attachment of antigen to solid phase follow by enzyme labeled antibody), 2- Indirect ELISA (Involve attachment of antigen to solid phase but the primary antibody isn’t labeled and secondary antibody is labeled with enzyme), 3- Sandwich ELISA (Involve attachment of capture antibody to solid phase follow by enzyme labeled antibody), 4- Competitive ELISA (Involve simultaneous addition of competing antibodies that decrease signal of samples when add secondary antibody) #geneticteacher
