Anti-CD20(93-1B3), 1mg/mL

Recognizes a protein of 30-33 kDa, which is identified as CD20 (Workshop V, Code CD20.4). 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.Primary antibodies are available purified, or with a selection of fluorescent CF(R) Dyes and other labels. CF(R) Dyes offer exceptional brightness and photostability. Note: Conjugates of blue fluorescent dyes like CF(R)405S and CF(R)405M are not recommended for detecting low abundance targets, because blue dyes have lower fluorescence and can give higher non-specific background than other dye colors. Concentration: 1 mg/mL Storage buffer: PBS, no BSA, no azide
