Anti-CD22(Myg13), 0.2mg/mL

This antibody ecognizes a protein of 130-140 kDa, identified as CD22 (also known as BL-CAM). CD22 expression is restricted to normal and neoplastic B cells and is absent from other haemopoietic cell types. In B-cell ontogeny, CD22 is first expressed in the cytoplasm of pro-B and pre-B cells, and on the surface as B cells mature to become IgD. It is not expressed by plasma cells, CD22 is found highly expressed in follicular mantle and marginal zone B-cells, and while germinal center B-cells are relatively weak. CD22 is a member of the immunoglobulin superfamily and serves as an adhesion receptor for sialic acid-bearing ligands expressed on erythrocytes and all leukocyte classes. It also associates with tyrosine kinases and play a role in signal transduction and B-cell activation.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: 0.2 mg/mL Storage buffer: PBS, 0.05% BSA, 0.05% azide
