| 背景 | B-cell receptor CD22 is a ~95 kDa protein. Most highly expressed siglec (sialic acid-binding immunoglobulin-like lectin) on B-cells that plays a role in various aspects of B-cell biology including differentiation, antigen presentation, and trafficking to bone marrow. Binds to alpha 2,6-linked sialic acid residues of surface molecules such as CD22 itself, CD45 and IgM in a cis configuration. Can also bind to ligands on other cells as an adhesion molecule in a trans configuration. Acts as an inhibitory coreceptor on the surface of B-cells and inhibits B-cell receptor induced signaling, characterized by inhibition of the calcium mobilization and cellular activation. Mechanistically, the immunoreceptor tyrosine-based inhibitory motif domain is phosphorylated by the Src kinase LYN, which in turn leads to the recruitment of the protein tyrosine phosphatase 1/PTPN6, leading to the negative regulation of BCR signaling. CD22 is the therapeutic target of inotuzumab ozogamicin (Besponsa). 1. Meyer, SJ. et al. (2021) Journal of immunology (Baltimore, Md. : 1950) 207, 1018-1032. PMID: 34330755 2. Law, CL. et al.

SDS-PAGE for Research Grade Anti-Human CD22 (M971).

Flow-cytometry using APC anti-human CD22 antibody. Daudi cells were stained with an irrelevant antibody (Blue Histogram) or an APC anti-human CD22 monoclonal antibody (Catalog: HB011076, Yellow Histogram) at a concentration of 5 µg/ml for 30 mins at RT. After washing, and cells analysed on a NovoCyte Flow Cytometer.

Flow-cytometry using FITC anti-human CD22 antibody. Daudi cells were stained with an irrelevant antibody (Blue Histogram) or an FITC anti-human CD22 monoclonal antibody (Catalog: HB011076, Yellow Histogram) at a concentration of 5 µg/ml for 30 mins at RT. After washing, and cells analysed on a NovoCyte Flow Cytometer.
