IL-12 (p35/p70) Monoclonal / PE / REA121

Product Details

Description	Interleukin-12 (IL-12) is a 70–75 kDa heterodimeric cytokine composed of a 40 kDa heavy chain and a 35 kDa light chain. It is produced mainly by monocytes and macrophages as well as dendritic cells, primarily in response to stimulation with bacterial or viral antigens. IL-12 has also been described to be produced by non-hematopoietic cells such as keratinocytes and epidermoid carcinomas. IL-12 displays various effects on both NK and T cells, playing an essential role in the interaction between innate and adaptive immunity: It induces the production of IFN-gamma alone or in synergy with IL-2, is a co-stimulator of both NK and T cell proliferation, and enhances cytolytic activity of both cell types. Moreover, IL-12 promotes the development of T helper 1 (Tʜ1)-specific immune responses by promoting the differentiation of CD4+ cells towards a Tʜ1 phenotype while inhibiting the production of Tʜ2 cells. The antibody clone REA121 reacts with the p35 kDa chain and the p70 kDa heterodimer of human IL-12, but not with IL-12 p40. It recognizes the same epitope as clone B-T21. \| Additional information: Clone REA121 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.
