{"product_id":"biolegend-101629","title":"Biolegend, 101629, APC\/Cyanine7 anti-mouse CD23 Antibody, 25μg","description":"\u003cp\u003eCD23 is a 45 kD protein also known as low affinity IgE Fc receptor, FcεRII, BLAST-2, Ly-42, or B6. It is a member of the Ig family, expressed on conventional B (but not B-1) cells and follicular dendritic cells. CD23 responds to high levels of IgE by downregulating IgE secretion.\u003cbr\u003e\n25μg\u003cbr\u003e\nVerified Reactivity: Mouse\u003cbr\u003e\nAntibody Type: Monoclonal\u003cbr\u003e\nHost Species: Rat\u003cbr\u003e\nImmunogen: Complex of IgE with Fcε receptor isolated from the mouse B hybridoma cell line O1.2B2\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 APC\/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: Red Laser (633 nm)\u003cbr\u003e\nApplication Notes: The B3B4 antibody is useful for blocking IgE activity in vivo. Additional reported applications (for the relevant formats) include: immunoprecipitation1, immunofluorescence microscopy, in vitro and in vivo blocking of ligand binding2-4, immunohistochemical staining of acetone-fixed frozen sections5, and spatial biology (IBEX)7,8.\u003cbr\u003e\nApplication References(PubMed link indicates BioLegend citation): Waldschmidt TJ, et al. 1988.
