{"product_id":"biolegend-313523","title":"Biolegend, 313523, Brilliant Violet 421™ anti-human\/mouse\/rat CD278 (ICOS) Antibody, 25tests","description":"\u003cp\u003eICOS, also known as inducible costimulatory molecule and H4, is a 47-57 kD protein. This protein is homologous to the CD28\/CTLA-4 proteins. ICOS is expressed on activated T cells and a subset of thymocytes. It is able to costimulate T cells proliferation. In addition, ICOS is involved in humoral immune responses (B cell germinal center formation). The ICOS ligand is B7h\/B7RP-1 or B7-H2. ICOS stimulation has been shown to potentiate TCR-mediated IL-4 and IL-10 production and has been proposed to play a role in Th2 cell development.\u003cbr\u003e\n25tests\u003cbr\u003e\nVerified Reactivity: Human, Mouse, Rat\u003cbr\u003e\nReported Reactivity: African Green, Baboon, Cynomolgus, Rhesus, Pig\u003cbr\u003e\nAntibody Type: Monoclonal\u003cbr\u003e\nHost Species: Armenian Hamster\u003cbr\u003e\nImmunogen: Mouse T cell clone D10.G4.1\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 Brilliant Violet 421™ 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.
