The Mouse CD22 Monoclonal Antibody (AF647 Conjugated, CY34.1) is a valuable research tool designed for the study of CD22, a cell surface protein with important implications in immune regulation and B cell function. This monoclonal antibody, conjugated with AF647 for fluorescent detection, is specially developed for use in flow cytometry and immunofluorescence applications, allowing for precise identification and analysis of CD22 expression in various cell populations.CD22 is a key regulator of B cell activation and survival, playing a crucial role in modulating immune responses and maintaining immune tolerance.
Dysregulation of CD22 has been implicated in various autoimmune diseases and B cell malignancies, making it a significant target for investigation in immunology and oncology research. This antibody provides researchers with a reliable tool for exploring the role of CD22 in different biological contexts, aiding in the advancement of knowledge on B cell biology and the development of potential therapies targeting CD22-related pathways.
Each lot of this antibody is quality control tested by flow cytometric analysis. The amount of the reagent is suggested to be used 5 µL of antibody per test (million cells in 100 µL staining volume or per 100 µL of whole blood). Please check your vial before the experiment. Since applications vary, the appropriate dilutions must be determined for individual use.

Background:
The Cy34.1 monoclonal antibody specifically binds to the B-lymphocyte differentiation antigen CD22 on strains having the Lyb-8.2 alloantigen (e.g., A, BALB/c, CBA, C3H/He, C57BL, C57L, C58, SJL, SWR, but not AKR, DBA/1, DBA/2, NZB, PL). CD22 is expressed at high levels on mature peripheral B lymphocytes (follicular and marginal zone), B-1 cells (CD5+ B cells), and plasma cells. It is a member of the Ig gene superfamily and associates with the B-cell antigen receptor. Its sialic acid- binding immunoglobulin-like lectin (siglec) extracellular region mediates B-cell adhesion to ligands on endothelial cells in the bone marrow. Its intracellular domain is phosphorylated after cross-linking of antigen receptor or MHC class II antigen. It is involved in negative regulation of B-cell activation and protection from autoimmunity. B-cell proliferative responses to LPS or anti-mouse Ig µ chain are augmented in the presence of Cy34.1 mAb.
