{"product_id":"biolegend-313561","title":"Biolegend, 313561, TotalSeq™-D0171 anti-human\/mouse\/rat CD278 (ICOS) Antibody, 10μg","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\n10μg\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 EDTA\u003cbr\u003e\nPreparation: The antibody was purified by chromatography and conjugated with TotalSeq™-D oligomer under optimal conditions.\u003cbr\u003e\nConcentration: 0.5 mg\/mL\u003cbr\u003e\nStorage \u0026amp; Handling: The antibody solution should be stored undiluted between 2°C and 8°C. Do not freeze.\u003cbr\u003e\nApplication: PG - Quality tested\u003cbr\u003e\nRecommended Usage: Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis and the oligomer sequence is confirmed by sequencing. TotalSeq™-D antibodies are compatible with Mission Bio’s Tapestri Single-Cell Sequencing Platform for simultaneous detection of DNA and Protein. To maximize performance, it is strongly recommended that the reagent be titrated for each application, and that you centrifuge the antibody dilution before adding to the cells at 14,000xg at 2 - 8°C for 10 minutes. Carefully pipette out the liquid avoiding the bottom of the tube and add to the cell suspension. For Proteogenomics analysis, the suggested starting amount of this reagent for titration is ≤ 1.0 µg per million cells in 100 µL volume. Refer to the corresponding TotalSeq™ protocol for specific staining instructions.

For example, for any technology platform Buyer uses with TotalSeq™, it is Buyer's sole responsibility to determine whether it has all necessary third party intellectual property rights to use that platform and TotalSeq™ with that platform.\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\nAdditional Product Notes: TotalSeq™-D reagents are designed to profile protein expression at single cell level. The Mission Bio Tapestri platform and sequencer (e.g. Illumina analyzers) are required.
