CD19 is expressed throughout B cell development from pre-B cells through mature B cells, and it is commonly used as a B cell lineage marker . It is required for the responsiveness of mature B cell to antigen stimulation, germinal center development, and antibody affinity maturation . The CD19 protein associates with the B cell antigen receptor (BCR), CD81, CD38, CD21, CD22, and IFITM1\/CD225\/Leu13. These associations enable CD19 to amplify B cell signaling  and reduce the threshold for antigen stimulation through the BCR.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eConcentration\u003c\/b\u003e: ≥ 1 mg\/mL\u003c\/p\u003e\u003cp\u003e\u003cb\u003eControl catalog number\u003c\/b\u003e:\u003c\/p\u003e\u003cp\u003e\u003cb\u003eImmunogen\u003c\/b\u003e:Recombinant Human CD19 protein\u003c\/p\u003e\u003cp\u003e\u003cb\u003eBuffer\u003c\/b\u003e:Sterile PBS, pH 7.2. \u0026lt; 1.0 EU per mg of the antibody as determined by the LAL method.\u003c\/p\u003e\u003cp\u003e\u003cb\u003ePurification method\u003c\/b\u003e:\u0026gt;98%, Protein A\/G purified\u003c\/p\u003e\u003cp\u003e\u003cb\u003eDilution\u003c\/b\u003e:FCM 2 μg\/mL(0.5×10\u003csup\u003e6\u003c\/sup\u003e-1×10\u003csup\u003e6\u003c\/sup\u003e cells)\u003c\/p\u003e\u003cp\u003e\u003cb\u003eGeneID\u003c\/b\u003e:930\u003c\/p\u003e","brand":"GeneBio Systems","offers":[{"title":"Default Title","offer_id":48654390427748,"sku":"GBS-F11270","price":222.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0558\/8588\/9636\/files\/no_image_default_image-jpeg_d111755e-6fa3-4fca-a236-c03ca10c38f7.jpg?v=1782787766","url":"https:\/\/www.genebiosystems.com\/en-de\/products\/af-le-purified-anti-human-cd19-antibody-4g7","provider":"GeneBio ","version":"1.0","type":"link"}
