Immunochemistry Analysis Using Chromogenic Substrates on Tissue Sections

Immunohistochemistry (IHC) is a highly sensitive protein detection technique developed using the principle of antigen-antibody binding reaction. With immunohistochemistry, it is possible to visualize the abundance, distribution, and localization of proteins in situ. This chapter discusses the standard protocols involved in IHC detection using chromogenic substrates, including pre-treatment of tissues, types of chromogenic substrates, and troubleshooting at various stages of the protocol.
