CD45RB antibody

Catalog No. ABIN94146

Product Details anti-CD45RB Antibody

Target: CD45RB

Reactivity: Human

Host: Mouse

Clonality: Monoclonal

Conjugate: This CD45RB antibody is un-conjugated

Application: Flow Cytometry (FACS), Immunohistochemistry (Paraffin-embedded Sections) (IHC (p))

Specificity: The antibody MEM-143 reacts with an extracellular epitope of CD45RB, a 180-240 kDa single chain type I membrane glycoprotein, variant of CD45 (CD45RB isoform). CD45RB is expressed on a subset of T lymphocytes, B lymphocytes, monocytes, macrophages, granulocytes and dendritic cells. The MEM-143 is therefore not neuraminidase sensitive like most other anti-CD45RB antibodies (including standard antibody MEM-55). The reactivity of the antibody MEM-143 can be blocked by a peptide including amino acids 79-88.

Cross-Reactivity (Details): Human

Purification: Purified by protein-A affinity chromatography.

Purity: > 95 % (by SDS-PAGE)

Immunogen: Human peripheral blood lymphocytes.

Clone: MEM-143

Isotype: IgG1

Application Details

Application Notes: Flow cytometry: Recommended dilution: 0.5-4 μg/mL. The staining pattern of the MEM-143 shows prominent differences from other anti-CD45RB reagents including standard antibody MEM-55, mostly as a result of the recognition of differences in glycosylation.
Immunohistochemistry (paraffin sections): Recommended dilution: 10 μg/mL, positive control: human tonsil.

Restrictions: For Research Use only

Handling

Background: CD45RB is an of a receptor-type protein tyrosine phosphatase, CD45 glycoprotein. CD45 is crucial in lymphocyte development and antigen signaling, serving as an important regulator of Src-family kinases, promotes cell survival by modulating integrin-mediated signal transduction pathway and is also involved in DNA fragmentation during apoptosis. CD45 isoforms differ in their extracellular domains, whereas they share identical transmembrane and cytoplasmic domains. These isoforms differ in their ability to translocate into the glycosphingolipid-enriched membrane domains and their expression depends on cell type and physiological state of the cell. CD45RB is expressed e.g. in microglia and inflammatory cells.,PTPRCR, T200RB
