{"product_id":"biolegend-621621","title":"Biolegend, 621621, PE\/Fire™ 700 anti-human CD279 (PD-1) Antibody, 25tests","description":"\u003cp\u003eProgrammed cell death protein 1 (PD-1), also known as CD279, is a 55 kD member of the immunoglobulin superfamily. CD279 contains the immunoreceptor tyrosine-based inhibitory motif (ITIM) in the cytoplasmic region and plays a key role in peripheral tolerance and autoimmune disease. CD279 is expressed predominantly on activated T cells, B cells, and myeloid cells. PD-L1 (B7-H1, CD274) and PD-L2 (B7-DC, CD273) are ligands of CD279 (PD-1) and are members of the B7 gene family. Evidence suggests overlapping functions for these two PD-1 ligands and their constitutive expression on some normal tissues and upregulation on activated antigen-presenting cells. Interaction of CD279 ligands results in inhibition of T cell proliferation and cytokine secretion.\u003cbr\u003e\n25tests\u003cbr\u003e\nVerified Reactivity: Human\u003cbr\u003e\nAntibody Type: Monoclonal\u003cbr\u003e\nHost Species: Mouse\u003cbr\u003e\nImmunogen: Recombinant human CD279 protein\u003cbr\u003e\nFormulation: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide and BSA (origin USA)\u003cbr\u003e\nPreparation: The antibody was purified by affinity chromatography and conjugated with PE\/Fire™ 700 under optimal conditions.\u003cbr\u003e\nConcentration: Lot-specific (to obtain lot-specific concentration and expiration, please enter the lot number in our Certificate of Analysis online tool.)\u003cbr\u003e\nStorage \u0026amp; Handling: The antibody solution should be stored undiluted between 2°C and 8°C, and protected from prolonged exposure to light.
