Product Images

Immunofluoscent Staining: BALB/c splenocytes were double-stained with Rat anti-Mouse CD22-R-PE and Rat anti-Mouse CD19-FITC (Clone 6D5). Small lymphocytes were gated and analyzed on a FACScan (TM) flow cytometer (BDIS, San Jose, CA). Amount Used: 0.3 ug/10e6 cells.

• Background: CD22, also known as Lyb-8, is a heterodimeric transmembrane glycoprotein and a member of a structurally related group of immunoglobulin (Ig) superfamily domain-containing proteins called the sialoadhesin family. It is detected in the cytoplasm early in B cell development (late pro-B cell stage), appears on the cell surface concomitant with IgD, and is found on most IgM+IgD+ mature B lymphocytes. Expression is lost with terminal differentiation of B cells and is absent on plasma cells. Activation of B cells via cross-linking of surface Ig increases CD22 expression. (Ref.1,2) CD22 associates with the B cell receptor (BCR) complex and mediates intercellular adhesion. (Ref.2-4) Its intracellular domain is phosphorylated after antigen receptor crosslinking and is involved in negative regulation of B-cell activation. (Ref.6-9)
