CD28 antibody (FITC)

Catalog No. ABIN2749055

Product Details anti-CD28 Antibody (FITC)

Target: CD28

Reactivity: Rat

Host: Mouse

Clonality: Monoclonal

Conjugate: This CD28 antibody is conjugated to FITC

Application: Flow Cytometry (FACS)

Specificity: The mouse monoclonal antibody JJ319 reacts with an extracellular epitope of CD28, a disulfide-linked homodimeric type I glycoprotein (monomer of Mw 44 kDa) which is a critical costimulatory receptor of T cells.

Cross-Reactivity (Details): Rat

Purification: Purified antibody is conjugated with fluorescein isothiocyanate (FITC) under optimum conditions and unconjugated antibody and free fluorochrome are removed by size-exclusion chromatography.

Immunogen: Mouse A20J B lymphoma cells transfected with rat CD28

Clone: JJ319

Background: CD28 Molecule,CD28 is the critical T cell costimulatory receptor which provides to the cell the important second activation signal by binding CD80 and CD86 that are expressed by antigen presenting cells. Besides its costimulation role CD28 functions in preventing T cells from anergic hyporesponsive state or from undergoing premature apoptotic cell death. CD28 is also expressed on human fetal NK cells and some NK cell lines, whereas on murine NK cells the CD28 expression is much broader.,Tp44
