Isotype
Mouse IgG1
Specificity
The antibody MEM-01 reacts with an extracellular epitope of CD22 (BL-CAM), a 130 kDa type I transmembrane glycoprotein (immunoglobulin superfamily) expressed in the cytoplasm of pro-B and pre-B lymphocytes, and on the surface of mature and activated B lymphocytes; it is lost on plasma cells, peripheral blood T lymphocytes, granulocytes and monocytes. The antibody MEM-01 cross-blocks the antibody OTH228 that recognizes uniquely epitope "E"; it does not cross-block antibodies RFB-4, CLB22/1 and CLB-BLy1.
Application
FC (QC tested)
Application details
Flow cytometry: The reagent is designed for analysis of human blood cells using 20 μl reagent / 100 μl of whole blood or 10
6
cells in a suspension. The content of a vial (2 ml) is sufficient for 100 tests.
Reactivity
Human, Non-human primates
Immunogen
Raji Burkitt's lymphoma cell line
Preparation
Purified antibody is conjugated with R-phycoerythrin (PE) under optimum conditions. Unconjugated antibody and free fluorochrome are removed by size-exclusion chromatography.
Formulation
Stabilizing phosphate buffered saline (PBS), pH 7.4, 15 mM sodium azide
Storage and handling
Store at 2-8°C. Protect from prolonged exposure to light. Do not freeze.

Antigen description
CD22, also known as Siglec-2 (sialic acid-binding immunoglobulin-like lectin-2) is a transmembrane glycoprotein binding alpha2,6-linked sialic acid-bearing ligands. Intracellular domain of CD22 recruits protein tyrosine phosphatase SHP-1 through the immunoreceptor tyrosine-based inhibitory motifs (ITIMs), thus setting a treshold for B cell receptor-mediated activation. CD22 also regulates B-cell response by involvement in controlling the CD19/CD21-Src-family protein tyrosine kinase amplification pathway and CD40 signaling. CD22 exhibits hallmarks of clathrin-mediated endocytic pathway.

Flow cytometry surface staining pattern of human peripheral whole blood stained using anti-human CD22 (MEM-01) PE antibody (20 μl reagent / 100 μl of peripheral whole blood).
Separation of human CD22 positive lymphocytes (red-filled) from CD22 negative lymphocytes (black-dashed) in flow cytometry analysis (surface staining) of human peripheral whole blood stained using anti-human CD22 (MEM-01) PE antibody (20 μl reagent / 100 μl of peripheral whole blood).
