Immunohistochemistry protocol - Avidin/Biotin Method (ABC)

The principle of ABC detection kits is based on the affinity of avidin (or streptavidin) for biotin. Indeed, abbreviation ABC stands for Avidin / Biotin Complex.   In general, the ABC detection kits are composed of: - A biotinylated secondary antibody - An Avidin / Enzyme Complex   The kits may or may not contain the blocking and dilution buffers and the substrate depending on the formats.
