Biological Significance
CD28 (Cluster of Differentiation 28) is one of the molecules expressed on T cells that provide co-stimulatory signals, which are required for T cell activation. CD28 is the receptor for B7.1 (CD80) and B7.2 (CD86). When activated by Toll-like receptor ligands, the B7.1 expression is upregulated in antigen presenting cells (APCs). The B7.2 expression on antigen presenting cells is constitutive. CD28 is the only B7 receptor constitutively expressed on naive T cells.
Biohazard Information
This product contains sodium azide as preservative. Although the amount of sodium azide is very small appropriate care must be taken when handling this product.
CD28 antibody (PE) was raised in hamster using CD28 costimulatory receptor as the immunogen.
Preparation and Storage
Store at 4 degree C.
Other Notes
Small volumes of anti-CD28 antibody vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

CD28: a type I plasma membrane protein Involved in T-cell activation, the induction of cell proliferation and cytokine production and promotion of T-cell survival. Binds to B7-1 and -2. Expressed in T cells and plasma cells, but not in less mature B cells. Six splice-variant isoforms have been described.

Protein type: Cell surface; Membrane protein, integral

Cellular Component: membrane; integral to membrane; plasma membrane; immunological synapse; lipid raft; external side of plasma membrane
