CD28 Antibodies

AND CD28 ELISA kits, CD28 Proteins

Many biological assays use antibodies to detect CD28, such as Western Blot (WB), ELISA, Flow Cytometry, Immunocytochemistry (IHC). These antibodies can be polyclonal or monoclonal, and react with CD28 in Human, Mouse, Rat, and many other animal samples. Boster Bio use mainly mouse and rabbit to develop CD28 antibodies...

We validate the specificity of these antibodies to CD28 by testing them on tissues known to express CD28 positively and negatively. Browse below to find the CD28 antibody that suites your experiment. We have 43 of these antibodies and many publications and validation images.

If you cannot find antibodies that fit your needs, contact us for making custom antibodies. We have a full suite of custom antibody services covering from research to diagnostic and therapeutic applications.

CD28 Overview

Facts about T-cell-specific surface glycoprotein CD28.

CD28 3D structure. Source: alphafold

T-cell-specific surface glycoprotein CD28 (CD28)

Involved in T-cell activation, the induction of cell proliferation and cytokine production and marketing of T-cell survival. Enhances the production of IL4 and IL10 in T-cells in conjunction with TCR/CD3 ligation and CD40L costimulation (PubMed:8617933).

Isoform 3 enhances CD40L-mediated activation of NF-kappa-B and kinases MAPK8 and PAK2 in T-cells (PubMed:15067037). .
