{"product_id":"new-product-222885","title":"CD19 Mouse monoclonal antibody","description":"\u003cp\u003eCD19 is a transmembrane glycoprotein that contains two extracellular immunoglobulin-like domains. CD19 is selectively expressed on the cell surface of B-lymphocytes, where it activates intracellular signaling cascades involving both Ras and phosphatidylinositol 3-kinase pathways. Activation of CD19 results in cross-linking of the membrane protein immunoglobulin chains and the subsequent association with Src family protein tyrosine kinases (PTK). Expression of CD19 is continuous throughout B-cell development and through terminal differentiation of B-cells into plasma cells. CD19 forms functional complexes with B-lymphocyte surface proteins, including integrin β1, CD21 and CD81, which are involved in regulating B-cell development.\u003c\/p\u003e","brand":"Bioworld","offers":[{"title":"100ul \/ Mouse \/ Human, mouse","offer_id":47661494108440,"sku":"MB9024","price":448.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/products\/BIOWORLD_501ea1e6-6438-419b-b7fe-cd25e08a297d.jpg?v=1707456529","url":"https:\/\/danabiosci.com\/products\/new-product-222885","provider":"Dana Bioscience","version":"1.0","type":"link"}
