Primary Antibodies, Secondary Antibodies, and Isotype Controls From R&D Systems & Novus Biological
An antibody is a Y shaped protein that is produced in the immune system and is designed to target a specific protein or molecule. Due to the highly specific nature of antibodies, they can be used as powerful tools for research. Over the years a variety of techniques and applications have been developed using antibodies. These include Immunoassays, Flow Cytometry, Immunohistochemistry, Western blotting and more.
R&D Systems offers a wide range of antibodies to cytokines, adhesion molecules, proteases, neurotrophic factors, stem cell factors, signal transduction molecules, and developmental proteins. Monoclonal and polyclonal antibodies are available with multiple labeled options or unlabeled. With over 20,000 antibody products validated in 25+ species and 15+ applications, our antibodies fit into all work flows.
