CD28 Antibodies
Cluster of differentiation 28 (CD28) is a 44 kDa disulfide-linked homodimeric surface glycoprotein that functions in T cell activation. Human CD28 protein is 220 amino acids (aa) in length with a calculated molecular weight of 25 kDa. CD28 is a costimulatory molecule that provides signals critical for naive T cell stimulation, cytokine production, proliferation, and survival. We offer CD28 antibodies that have been featured in 45+ publications. Browse our catalog of recombinant monoclonal, monoclonal, polyclonal, and CD28-conjugated antibodies. Validated research applications for these CD28-antibodies include Blocking/Neutralizing, CyTOF-ready, ELISA, Flow Cytometry, Functional, ICC, Immunofluorescence, IHC-Frozen, IHC-Paraffin, Immunoprecipitation, and Western Blot. Our CD28 antibodies are reactive in many species such as Human, Mouse, Rat, Bovine, Porcine, Primate, and Sheep. Choose the anti-CD28 antibody best suited for your research needs by viewing the technical details, images, references, reviews, and related products. Each CD28 antibody is fully covered by Novus’ Guarantee+ to give you peace of mind and support when you need it.
