Anti-CD20(B9E9), CF568 conjugate, 0.1mg/mL

Recognizes a protein of 33-37 kDa, identified as CD20 (Workshop V, Code CD20.12). B9E9 recognizes extracellular domain of CD20. The epitope is similar to or identical to that recognized by other CD20 antibodies including Leu-16 and B1. This MAb can be used for immunophenotyping of leukemia and malignant cells, B lymphocyte detection in peripheral blood, B cell localization in tissues and B lymphocyte purification by immunosorbent methods. CD20 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. 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 a 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: 0.1 mg/mL Storage buffer: PBS, 0.1% BSA, 0.05% azide
