Immunohistochemistry or Immunocytochemistry is the name of the method for localizing specific antigens in tissue or cells using antibodies, enzyme conjugates and substrate-chromogens. The antigen-antibody reaction can be evidenced with an optical microscope. The antibodies can be polyclonal or monoclonal (usually from mouse or rabbit) in origin. These non-infectious biological reagents are used by research and clinical laboratories to detect the presence of infectious agents, cancer and other proteins of interest. Bio SB offers a wide range of rabbit and mouse monoclonal and polyclonal antibodies for IVD and ASR applications as well as complete detection systems or their components. We offer both HRP and AP kits: The ImmunoDetector kits use the traditional 3-step Biotin-Streptavidin-Enzyme / Substrate-Chromogen technology while the PolyDetector and CytoDetector kits have been developed using a proprietary tandem hyperlabelling technology used to directly label immunoglobulins with enzymes. This ensures consistent and reproducible immunostaining for all types of nuclear, cytoplasmic and membranal antigens, in different types of tissues or cells. We also offer for RUO, Complete CytoDetector HRP/DAB kits for HPV and Complete PolyDetector HRP/DAB kits for ER/PR, HER-2 neu and CD117 that include all reagents, solutions, tissue controls and reagent controls.
