Background	T-cell-specific surface glycoprotein CD28 is a ~25 kDa protein. Receptor that plays a role in T-cell activation, proliferation, survival and the maintenance of immune homeostasis. Functions not only as an amplifier of TCR signals but delivers unique signals that control intracellular biochemical events that alter the gene expression program of T-cells. Stimulation upon engagement of its cognate ligands CD80 or CD86 increases proliferation and expression of various cytokines in particular IL2 production in both CD4(+) and CD8(+) T-cell subsets. Mechanistically, ligation induces recruitment of protein kinase C-theta/PRKCQ and GRB2 leading to NF-kappa-B activation via both PI3K/Akt-dependent and -independent pathways. In conjunction with TCR/CD3 ligation and CD40L costimulation, enhances the production of IL4 and IL10 in T-cells. 1. Gimmi, CD. et al.

Flow Cytometry

Flow-cytometry using APC anti-human CD28 antibody. RPMI-8226 cells were stained with an irrelevant antibody (Green Histogram) or an APC anti-human CD28 antibody monoclonal antibody (Catalog # HY422237, Red Histogram) at a concentration of 5 µg/ml for 30 mins at RT. After washing, cells analysed on a NovoCyte Flow Cytometer.
