Immunohistochemistry Dual Staining Kit

Apply the basic principles of immunology to the antigen-antibody reaction, that is, the principle of specific binding of antigen and antibody. Through chemical reactions, the poly-HRP enzyme of the labeled antibody catalyzes DAB (brown product) and TY (red chromogen specific conjugate) to develop colors respectively. To determine the intracellular antigens (polypeptides and proteins) of tissues and conduct localization, qualitative and quantitative research on them. HRP catalyzes the formation of brown deposits from diaminobenzidine (DAB) at antigenic sites. The HRP catalytic intermediate TY permanently labels the antigen and achieves signal amplification. The red chromogen specifically recognizes the TY product (covalent binding), thus achieving the accumulation of red signals and completing red color development.
