{"product_id":"cst-69989s","title":"CST,  69989S, Total PD-1 Matched Antibody Pair","description":"Matched Antibody Pair for studying PDCD1 mouse in the research area.\n\n\u003cb\u003eProduct Usage Information\u003c\/b\u003e\nMatched Antibody Pairs consist of capture and detection antibodies that bind to non-overlapping epitopes. For specific identification of the capture and detection antibodies in this pair, please refer to the data figure caption. Optimal dilutions\/concentrations should be determined by the end user.\n\u003cb\u003eFormulation\u003c\/b\u003e\nSupplied in 1X PBS (10 mM Na 2 HPO 4 , 3 mM KCl, 2 mM KH 2 PO 4 , and 140 mM NaCl (pH 7.8)). BSA and Azide Free.\n\u003cb\u003eStorage\u003c\/b\u003e\nStore at -20ºC. This product will freeze at -20ºC so it is recommended to aliquot into single-use vials to avoid multiple freeze\/thaw cycles . A slight precipitate may be present and can be dissolved by gently vortexing. This will not interfere with antibody performance.\n\u003cb\u003eBackground\u003c\/b\u003e\nThe programmed cell death 1 protein (PD-1, PDCD1, CD279) is a member of the CD28 family of immunoreceptors that regulate T cell activation and immune responses (1-3). The PD-1 protein contains an extracellular Ig V domain, a transmembrane domain, and a cytoplasmic tail that includes an immunoreceptor tyrosine-based inhibitory motif (ITIM) and an immunoreceptor tyrosine-based switch motif (ITSM). PD-1 is activated by the cell surface ligands PD-L1 and PD-L2 (4). Upon activation, PD-1 ITIM and ITSM phosphorylation leads to the recruitment of the protein tyrosine phosphatases SHP-1 and SHP-2, which suppress TCR signaling (5-7). In addition to activated T cells, PD-1 is expressed in activated B cells and monocytes, although its function in these cell types has not been fully characterized (8). The PD-1 pathway plays an important role in immune tolerance (3); however, research studies show that cancer cells often adopt this pathway to escape immune surveillance (9). Consequently, blockade of PD-1 and its ligands is proving to be a sound strategy for neoplastic intervention (10).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nCD279; Ly101; mPD-1; PD-; PD-1; Pd1; Pdc; Pdc1; Pdcd1; programmed cell death 1; programmed cell death 1 protein; Programmed cell death protein 1; Protein PD-1\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: M","brand":"CST","offers":[{"title":"Default Title","offer_id":46800319578281,"sku":"69989S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-69989s","provider":"Iright","version":"1.0","type":"link"}
