CD137 Monoclonal / PE / REA765

Product Details

Description	Clone REA765 recognizes the human CD137 antigen, a 30 kDa glycoprotein of the tumor necrosis factor (TNF) receptor superfamily, a group of cytokines that can cause cell death (apoptosis). CD137 is mainly expressed on activated CD4+ and CD8+ T cells, activated B cells, and natural killer cells, but can also be found on resting monocytes and dendritic cells. As a costimulatory molecule it is involved in the activation and survival of CD4+ or CD8+ T cells and NK cells. CD137 has been described to be a suitable marker for antigen-specific activation of human CD8+ T cells, as it is not expressed on resting CD8+ T cells and its expression is reliably induced after 24 hours of stimulation. \| Additional information: Clone REA765 displays negligible binding to Fc receptors.

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.
