CD69 Monoclonal / APC / H1.2F3

Product Details

Description	Clone H1-2F3 recognizes mouse CD69, a type II integral membrane protein with a C-type lectin domain. CD69 is expressed as a homodimer composed of heavily glycosylated subunits. CD69 is rapidly induced upon activation of T and B cells, neutrophils, and NK cells, which is why CD69 has been mostly regarded as an activation marker. The precise role of CD69 in immunity has not been determined because its ligand is unknown. Freshly prepared thymocytes undergoing selection events express CD69, and regulatory roles for CD69 expression in T-cell development in the thymus have been suggested. However, phenotypical analysis in previous studies using CD69-deficient mice has revealed that CD69 does not appear to be required for the development of CD4 T cells. CD69 is also expressed on platelets. Recent studies have shown that CD69 is constitutively expressed by tissue-resident Th memory cells and that its function is essential for the generation of professional resting memory Th cells.

About CD69
This gene encodes a member of the calcium dependent lectin superfamily of type II transmembrane receptors. Expression of the encoded protein is induced upon activation of T lymphocytes, and may play a role in proliferation. Furthermore, the protein may act to transmit signals in natural killer cells and platelets. [provided by RefSeq, Aug 2011]

About APC
Allophycocyanin (APC) is a fluorescent protein derived from cyanobacteria and red algae and a potent donor fluorophore to create tandem dyes that can be excited off the 633-640 nm laser. APC has an excitation peak at 650 nm and a emission peak at 660 nm.
