CD22, also known as Siglec-2, is a B cell-specific membrane protein involved in regulating B cell activation and signaling.This monoclonal antibody is conjugated with PE/Cyanine5 for easy detection and analysis in flow cytometry applications. It is ideal for identifying and studying CD22 expression in mouse samples, making it a valuable tool for immunology and B cell research.
The specificity and sensitivity of this antibody make it a reliable choice for investigating the role of CD22 in various cellular processes, including B cell development, activation, and immune response modulation. Its use can contribute to a better understanding of B cell function and the development of targeted therapies for B cell-related disorders.Overall, the Mouse CD22 Monoclonal Antibody (PE/Cyanine5 Conjugated, CY34.1, AGEL0732) provides researchers with a powerful tool to advance their studies in immunology, B cell biology, and related fields.
Each lot of this antibody is quality control tested by flow cytometric analysis. Please check your vial before the experiment. Since applications vary, the appropriate dilutions must be determined for individual use. We suggest each investigator should titrate the reagent to obtain optimal results [The recommended concentration is 0.1-1 μg/106 cells in 100 μL volume].

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.
