Blocking with sera or a protein blocking reagent prevents non-specific binding of antibodies to tissue or to Fc receptors. Theoretically, any protein that does not bind to the target antigen can be used for blocking. In practice, some proteins bind more readily to non-specific sites. Serum is a common blocking agent as … See more When staining mouse tissues with mouse primary antibodies, there is often high background as the anti-mouse secondary antibody binds to endogenous mouse IgG and Fc receptors. This background binding can be reduced … See more Chromogenic detection methods usually use an enzyme linked directly, or indirectly, to a secondary antibody to visualize antibody localization. If the enzyme is naturally … See more If a biotin-based detection system is used, blocking endogenous biotin is recommended.
