{"product_id":"biolegend-104904","title":"Biolegend, 104904, Biotin anti-mouse\/rat CD81 Antibody, 500μg","description":"\u003cp\u003eCD81 is a 26 kD non-glycosylated member of the tetraspanin superfamily (TM4SF), also known as TAPA-1. CD81 is expressed on T and B cells, NK cells, dendritic cells, thymocytes, endothelial cells, and fibroblasts. CD81 induces B cell adhesion via the VLA-4 integrin and has been shown to play a role in early T cell development. CD81 associates with several other cell-surface proteins in a multimolecular complex, including CD19, CD21, CD20, CD37, CD53, and CD82 in B cells, and CD4, CD8 and CD82 in T cells.\u003cbr\u003e\n500μg\u003cbr\u003e\nVerified Reactivity: Mouse, Rat\u003cbr\u003e\nAntibody Type: Monoclonal\u003cbr\u003e\nHost Species: Armenian Hamster\u003cbr\u003e\nImmunogen: CD81+ mouse B lymphoma 38C13\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 biotin 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: 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 106 cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.\u003cbr\u003e\nApplication Notes: The Eat-2 antibody reacts with mouse and rat CD81. Additional reported applications (for the relevant formats) include: immunoprecipitation1,2, Western blotting1,2, induction of homotypic adhesion of B lymphocytes1, stimulation of B cells undergo early apoptotic events1, and promotion of T cell motility2.\u003cbr\u003e\nApplication References(PubMed link indicates BioLegend citation): 1.
