{"product_id":"v8375-20ug","title":"CD20 Antibody \/ MS4A1","description":"\u003cp\u003eRecognizes a protein of 30-33kDa, which is identified as CD20 (Workshop V; Code CD20.12. Workshop IV; Code B17). It recognizes an extracellular domain of CD20. It is a non-Ig differentiation antigen of B-cells and its expression is restricted to normal and neoplastic B-cells, being absent from all other leukocytes and tissues. CD20 is expressed by pre B-cells and persists during all stages of B-cell maturation but is lost upon terminal differentiation into plasma cells. The protein passes through the membrane 4 times with both ends in cytoplasm and exposes one short and one longer loop to the external environment. CD20 is not glycosylated in resting B-cells and its cytoplasmic domains are differentially phosphorylated upon activation. It acts as calcium channel involved in B cell activation and cell cycle progression.\u003c\/p\u003e","brand":"NSJ Bioreagents","offers":[{"title":"20 ug \/ Mouse","offer_id":49429996765464,"sku":"V8375-20UG","price":249.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/danabiosci.com\/products\/v8375-20ug","provider":"Dana Bioscience","version":"1.0","type":"link"}
