Lag-3 / PE / REA351
Product Details
| Description | Clone REA351 recognizes the human CD223 antigen, a single-pass type I membrane protein also known as lymphocyte activation gene 3 protein (LAG-3). CD223 is a CD4 homolog with four extracellular Ig superfamily domains. Similar to CD4, CD223 oligomerizes at the surfaces of T cells and binds to MHC II on antigen presenting cells but with significantly higher affinity than CD4. CD223 is expressed on activated CD4+ and CD8+ T lymphocytes where it associates with the CD3–TCR complex at the cell surface and negatively regulates signal transduction. As a consequence, it negatively regulates T cell proliferation, function, and homeostasis. There is also increasing evidence of its involvement in regulatory function of tumor-infiltrated T cells in cancer, such as in Hodgkin’s lymphomas and in prostate cancer. CD223 is also expressed on activated NK cells, B cells, and plasmacytoid dendritic cells. | Additional information: Clone REA351 displays negligible binding to Fc receptors. | |

About Lag-3
Lymphocyte-activation protein 3 belongs to Ig superfamily and contains 4 extracellular Ig-like domains. The LAG3 gene contains 8 exons. The sequence data, exon/intron organization, and chromosomal localization all indicate a close relationship of LAG3 to CD4. [provided by RefSeq, Jul 2008]

About PE
Phycoerythrin (PE, R-PE) is a red-emitting fluorescent protein-chromophore complex that can be excited the 488-nm blue, 532-nm green, or 561-nm yellow-green laser with increasing efficiency and captured with a 586/14 nm bandpass filter. PE has an excitation peak at 565 nm and an emission peak at 578 nm. PE is 240kD in size and has an extinction coefficient of ~2x10^6 which makes it one of the brightest fluorophores available and a potent donor upon which to build tandem fluorophores with longer Stoke's Shifts.
