CD28 antibodies – functional grade, mouse

CD28 antibodies – functional grade, mouse

Clone: 37.51
The CD28 antibody is specific for the mouse CD28 costimulatory molecule, expressed on most thymocytes, CD4
and CD8
T cells, and natural killer (NK) cells. Ligation of CD28 with CD80 (B7-1) and CD86 (B7-2) provides a costimulatory signal for T cell activation. Clone 37.51 has been shown to activate T cells in combination with CD3.
Activation and proliferation of T cells can be induced by interaction of the T cell receptor with peptide-MHC complexes. The T cell receives a signal transduced through the CD3 complex. Cytokines or other costimulatory signals from accessory cells are required in addition. Activated T cells can be used for any downstream processes, such as cytokine analysis or immunoprecipitation. Cells can also be transfected with high efficiency.


The CD28 antibodies – functional grade are suited for functional assays, for example,
in vitro
activation and expansion of T cells in combination with CD2 and CD3 pure – functional grade antibodies, or CD2- and CD3-Biotin – functional grade antibodies, and Anti-Biotin MACSiBead™ Particles, cell culture grade.
