{"product_id":"biolegend-396303","title":"Biolegend, 396303, Alexa Fluor® 647 anti-human CD19 Antibody, 25μg","description":"\u003cp\u003eCD19 is a 95 kD type I transmembrane glycoprotein also known as B4. It is a member of the immunoglobulin superfamily expressed on B-cells (from pro-B to blastoid B cells, absent on plasma cells) and follicular dendritic cells. CD19 is involved in B cell development, activation, and differentiation. CD19 forms a complex with CD21 (CR2) and CD81 (TAPA-1), and functions as a BCR co-receptor.\u003cbr\u003e\n25μg\u003cbr\u003e\nVerified Reactivity: Human\u003cbr\u003e\nAntibody Type: Monoclonal\u003cbr\u003e\nHost Species: Mouse\u003cbr\u003e\nImmunogen: Recombinant human CD19\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 Alexa Fluor® 647 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, and protected from prolonged exposure to light.
