General description

B-cell receptor CD22 (UniProt P20273; also known as B-lymphocyte cell adhesion molecule, BL-CAM, Sialic acid-binding Ig-like lectin 2, Siglec-2, T-cell surface antigen Leu-14) is encoded by the Cd22 (also known as A530093D23, Lyb-8, Lyb-8a, Lyb8, Siglec2) gene (Gene ID 12483) in murine species. Murine CD22 (mCD22) is a B cell-associated adhesion protein with seven extracellular Ig-like domains that has 62% amino acid homology to its human orthologue. CD22 is expressed at multiple stages during B cell ontogeny. Cytoplasmic hCD22 can be detected at the pro-B and pre-B, whereas expression of surface hCD22 tightly correlates with that of surface immunoglobulins (sIg), especially that of sIgD. Expression of hCD22 ceases upon B cell activation and terminal differentiation into plasma cells. Only the CD22+ subpopulation among sIgM+ tonsillar B cells can be stimulated by sIg cross-linking to induce intracellular calcium, which can be further enhanced by anti-CD22 treatment prior to sIg cross-linking. Crosstalk between CD22 and sIgM is also supported by the finding that CD22 can associate with sIgM and cross-linking of sIg can stimulate rapid tyrosine phosphorylation of CD22.

Splenocytes from mouse strain B10.D2

Application

Flow Cytometry Analysis: A representative lot detected the exogenously expressed mCD22, but not mCD40, on the surface of respective BHK transfectants (Law, C.L., et al. (1993). J. Immunol. 151(1):175-187).
Flow Cytometry Analysis: A representative lot selectively detected the Lyb-8.2 allelic form of Cd22 on sIgM-positive B lymphocytes from BALB/c mice, but not the Lyb-8.1 allelic form of Cd22 expressed on B lymophocytes from DBA/2J mice (Law, C.L., et al. (1993). J. Immunol. 151(1):175-187).
Immunoprecipitation Analysis: A representative lot immunoprecipitated the Lyb-8.2 allelic form of Cd22 from the splenocytes of B10.D2 mouse strain (Symington F.W., et al. (1982). Immunogenetics. 16(5):381-391).

This Anti-CD22 Antibody, clone CY34 is validated for use in Flow Cytometry and Immunoprecipitation for the detection of CD22.

Biochem/physiol Actions

Murine Cd22 gene is also known as Lyb-8. The epitope detected by clone CY34 is not expressed by all strains of mice due to Cd22 polymorphisms. Clone CY34 is known to react with Cd22 expressed on splenocytes from murine strains B10.D2 and BALB/c, C57BL/6, but not DBA/2J. Consequently, the allelic form of Cd22 from DBA/2J is designated as mCD22.1/Lyb-8.1 to distinquish it from the form of Cd22 recognized by clone CY34, originally designated as Lyb-8.2 (PMID 8100843 & 6984010).

"Mods – modifications – small alterations can have a big impact on form and function. In the motorsports world, stock vehicles are modified to enhance their performance. Modifications, or mods, to the engine, drive train, intake and exhaust components add up to provide phenomenal performance gains that can be measured as horsepower and torque increases, which yield a competitive advantage, and result in reduced run times. In biology, proteins undergo modifications that alter their function. Some proteins require the modifications in order to perform their function effectively, whether it’s a pro-protein that is cleaved to produce an active enzyme, or a protein that is phosphorylated to facilitate a signaling process. Other proteins, such as histones, undergo modifications that regulate gene expression and alter cellular function. There are several post translational modifications such as acetylation, methylation, phosphorylation, and ubiquitination that impact protein function and activity. As a result, the analysis of proteins and their post-translational modifications are particularly important for the study of normal and disease-associated processes. New antibodies to detect phospho Histidines are now available from EMD Millipore."
