CD22 polyclonal, anti-human, mouse, rat

Protein Family: CAM Ligands, Cell Adhesion Molecules, Cellular Antigens, Glycan Binding Proteins

Pathway and Disease: Immune System, Signaling Molecules and Interaction

Description:
CD22 antigen is expressed in the cytoplasm of pro-B and pre-B cells, and on the surface of mature B lymphocytes. CD22 expression is increased after activation and lost at the terminal stage of B cell differentiation. Most B cell leukemias and lymphomas also express CD22. CD22 is not expressed in T cells, monocytes and granulocytes. CD22 is an early marker for B-ALL and hairy-cell leukemia diagnostic. CD22 is an adhesion molecule that amplifies the signal of B cell activation. CD22 ligands are CD45RO antigen on T cells and CD75 antigen on B cells participating in the homotopic interaction of T and B cells.

Alternate Names: B-cell receptor CD22, Sialic acid-binding Ig-like lectin 2, Siglec-2, Leu-14, B-lymphocyte cell adhesion molecule, BL-CAM, CD22, SIGLEC2
