Product Specific Information
This antibody reacts with the extracellular domain of mouse CD28 costimulatory receptor, a 45 kDa homodimeric protein expressed by thymocytes, mature T cells, and NK cells.
Endotoxin level is less than 0.01 EU/µg of protein (LAL test).
Functional Application: In vitro and in vivo T cell costimulation.
Target Information
CD28 antigen is a 44 kDa disulfide-linked homodimeric T cell surface glycoprotein belonging to the immunoglobulin superfamily. It is constitutively expressed on most peripheral blood T lymphocytes and acts as a critical costimulatory receptor by binding CD80/CD86 on antigen-presenting cells.
CD28 prevents T cells from entering an anergic or apoptotic state and is expressed on all CD4+ and CD8+ T cells in murine peripheral lymphoid organs and blood.
In the thymus, expression is highest on immature CD3-, CD8+, and CD4+8+ cells.
Diseases associated with CD28 dysfunction include mycosis fungoides and Sezary’s disease.
