Immunohistochemistry or IHC is a mainstay immunoassay for many laboratories and is used to demonstrate the presence or absence of important proteins, detect post-translational modifications, diagnosis of disease and more. Rockland produces highly active antibodies and conjugates for use in immunohistochemistry experiments. Rockland also produces high quality reagents for the setup and detection in IHC experiments. Protect your experiments with Rockland antibodies. Compromise elsewhere.
Immunohistochemistry uses both immunological and biochemical techniques to examine distinct tissue sections by the use of labeled antibodies interacting with target antigens. A visible label or stain is used to visualize the antibody antigen interaction. IHC allows for the visualization of distinctive cellular components of cells and is frequently used by pathologists and in diagnostics. Rockland offers Custom Immunohistochemistry Studies for clients that desire that service.
The antigen is fixed and adhered to a glass microscope slide. Formaldehyde fixation is suggested as the routine initial method of choice for tissue and cell fixation, but other methods are also suitable. Background staining is reduced by with a blocking buffer to block non-specific sites to which the antibodies may bind. Rockland offers common blocking buffers including BSA, normal serum, non-fat dry milk, and an optimized proprietary blocking buffer.
Labeling is achieved by the reaction of a primary antibody with the immobilized antigen to form an antigen-antibody complex. A second biotinylated antibody specific for the primary antibody host species reacts with the complex. Streptavidin conjugated to the enzyme peroxidase or alkaline phosphatase reacts with this complex. Finally, substrate (view substrates) is added causing a reaction with the enzyme causing colored precipitate to form on the slide at the location of the antigen. The slide is viewed through a standard light microscope and photographed. A common manipulation in IHC fixing is use of the antigen retrieval technique, a simple method of heating or boiling paraffin-embedded tissue sections to enhance the observed signal. See Rockland’s IHC experimental protocol.
