{"product_id":"v8656-20ug","title":"CD19 Antibody","description":"\u003cp\u003eCD19 is a transmembrane glycoprotein that contains two extracellular immunoglobulin-like domains. CD19 is present in both benign and malignant B-cells and is considered to be the most reliable surface marker of this lineage over a wide range of maturational stages. In normal lymphoid tissue, CD19 is observed in germinal centers, in mantle zone cells, and in scattered cells of the inter-follicular areas. Anti-CD19 exhibits an overall immunoreactivity pattern similar to those of the antibodies against CD20 and CD22. However, in contrast to CD20, expression of CD19 is continuous throughout B-cell development and through terminal differentiation of B-cells into plasma cells. Anti-CD19 positivity is seen in the vast majority of B-cell neoplasms commonly at a lower intensity than normal B-cell counterparts. Plasma cell neoplasms are nearly always negative, as are T-cell neoplasms.\u003c\/p\u003e","brand":"NSJ Bioreagents","offers":[{"title":"20 ug \/ Mouse","offer_id":49429884141848,"sku":"V8656-20UG","price":249.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/get_image_17835e39-46df-4c96-b549-8207c834d842.jpg?v=1733308610","url":"https:\/\/danabiosci.com\/products\/v8656-20ug","provider":"Dana Bioscience","version":"1.0","type":"link"}
