CD4 Antibodies

CD4 (cluster of differentiation 4) is a single chain type I transmembrane glycoprotein belonging to the immunoglobin (Ig) superfamily. CD4 has a theoretical molecular weight of 55 kDa and is expressed on most thymocytes and a subset of mature T lymphocytes. CD4 functions in T cell development and has a diverse role in innate immunity. We offer highly rated antibodies to detect CD4 that have been cited in 80+ publications. Browse our extensive catalog for recombinant monoclonal antibodies, monoclonal antibodies, polyclonal antibodies, and CD4-conjugated antibodies. Validated research applications for our CD4 antibodies include Blocking/Neutralizing, CyTOF-ready, ELISA, Enzyme Immunoassay, Flow Cytometry, ICC, Immunofluorescence, IHC-Frozen, IHC-Paraffin, Immunoprecipitation, Simple Western, and Western Blot. Our CD4 antibodies are used in a variety of model species including Human, Mouse, Rat, Bovine, Chicken, Feline, Goat, Primate, Rabbit, Sheep, and more. Choose the anti-CD4 antibody best suited for your research needs by viewing the technical details, images, references, reviews, and related products. Each CD4 antibody is fully covered by Novus’ Guarantee+ to give you peace of mind and support when you need it.
