{"product_id":"biolegend-313519","title":"Biolegend, 313519, PE\/Cyanine7 anti-human\/mouse\/rat CD278 (ICOS) Antibody, 25μg","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\n25μg\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.\u003cbr\u003e\nPreparation: The antibody was purified by affinity chromatography and conjugated with PE\/Cyanine7 under optimal conditions.\u003cbr\u003e\nConcentration: 0.2 mg\/ml\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. Do not freeze.\u003cbr\u003e\nApplication: FC - Quality tested\u003cbr\u003e\nRecommended Usage: Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤0.25 µg per million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.\u003cbr\u003e\nExcitation Laser: Blue Laser (488 nm)Green Laser (532 nm)\/Yellow-Green Laser (561 nm)\u003cbr\u003e\nApplication Notes: The C398.4A antibody is useful for flow cytometric analysis and is able to costimulate T cell activation and proliferation. Additional reported applications (for the relevant formats) include: immunoprecipitation1, in vitro costimulation of T cell activation1,3,4, and spatial biology (IBEX)5,6. The LEAF™ purified antibody (Endotoxin \u0026lt; 0.1 EU\/µg, Azide-Free, 0.2 µm filtered) is recommended for functional assays (Cat. No. 313512).\u003cbr\u003e\nApplication References(PubMed link indicates BioLegend citation): Redoglia V, et al. 1996. Eur. J. Immunol. 26:2781. (FC IP Costim) Yagi J, et al. 2003. J.
