{"product_id":"rq4156","title":"CD19 Antibody \/ B-lymphocyte marker","description":"\u003cp\u003eB-lymphocyte antigen CD19, also known as CD19 (Cluster of Differentiation 19), is a protein that in humans is encoded by the CD19 gene. It is found on the surface of B-cells, a type of white blood cell. Lymphocytes proliferate and differentiate in response to various concentrations of different antigens. The ability of the B cell to respond in a specific, yet sensitive manner to the various antigens is achieved with the use of low-affinity antigen receptors. The CD19 gene encodes a cell surface molecule that assembles with the antigen receptor of B lymphocytes in order to decrease the threshold for antigen receptor-dependent stimulation.\u003c\/p\u003e","brand":"NSJ Bioreagents","offers":[{"title":"100 ug \/ Rabbit","offer_id":49476153803032,"sku":"RQ4156","price":439.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/get_image_9e5d26bb-939e-4dc6-b292-e3ea02c14a01.jpg?v=1734468439","url":"https:\/\/danabiosci.com\/products\/rq4156","provider":"Dana Bioscience","version":"1.0","type":"link"}
