Description Clone REA147 recognizes CD158b2, a killer cell immunoglobulin-like inhibitory receptor (KIR). Expressed by natural killer (NK) cells and a subset of T cells, KIR family of receptors are transmembrane glycoproteins and interact with MHC class I molecules. This interaction allows the KIR receptors to modulate the killing function of cells bearing them. The KIR proteins are categorized by the number of extracellular immunoglobulin domains (2D or 3D) and by the length (long (L) or short (S)) of the cytoplasmic domain. KIR proteins with the long cytoplasmic domain, such as CD158b2, transduce inhibitory signals via an immune tyrosine-based inhibitory motif (ITIM). | Additional information: Clone REA147 displays negligible binding to Fc receptors. |
About CD158b2 and PE
CD158b2 Killer cell immunoglobulin-like receptors (KIRs) are transmembrane glycoproteins expressed by natural killer cells and subsets of T cells. The KIR genes are polymorphic and highly homologous and they are found in a cluster on chromosome 19q13.4 within the 1 Mb leukocyte receptor complex (LRC). The gene content of the KIR gene cluster varies among haplotypes, although several "framework" genes are found in all haplotypes (KIR3DL3, KIR3DP1, KIR3DL4, KIR3DL2). The KIR proteins are classified by the number of extracellular immunoglobulin domains (2D or 3D) and by whether they have a long (L) or short (S) cytoplasmic domain. KIR proteins with the long cytoplasmic domain transduce inhibitory signals upon ligand binding via an immune tyrosine-based inhibitory motif (ITIM), while KIR proteins with the short cytoplasmic domain lack the ITIM motif and instead associate with the TYRO protein tyrosine kinase binding protein to transduce activating signals. The ligands for several KIR proteins are subsets of HLA class I molecules; thus, KIR proteins are thought to play an important role in regulation of the immune response.

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.
