Protocol
Specificity / Sensitivity
CD69 (H1.2F3) Hamster mAb (PE-Cy7® Conjugate) recognizes endogenous levels of total CD69 protein. This antibody detects an epitope within the extracellular domain.
Species Reactivity:
Mouse
Source / Purification
This monoclonal antibody was purified from tissue culture supernatant via affinity chromatography. The purified antibody was conjugated under optimal conditions, with unreacted dye removed from the preparation.
Background
CD69, also known as Leu-23, is a type II transmembrane glycoprotein that is expressed on the surface of T cells, B cells, and NK cells (1,2). This phosphorylated disulfide-linked 28 to 32-kDa homodimer is constitutively expressed on a subset of thymocytes and platelets. It also acts as an activation antigen of lymphocytes, NK cells, neutrophils, and eosinophils (1-6). Studies have shown that stimulation of the T cell receptor (TCR) increases the expression of CD69 on the cell surface. The ability to detect the level of CD69 expression after TCR activation makes CD69 an ideal indicator of T cell activation (1).
The H1.2F3 antibody is widely used as a marker for T cell activation (7).
