Invitrogen™ CD10 Monoclonal Antibody (eBioCB-CALLA (CB-CALLA)), PE, eBioscience™

Description

Description: The eBioCB-CALLA monoclonal antibody recognizes human CD10 (CALLA, NEP, enkephalinase, Neprilysin), which is a 100 kDa, type II cell surface glycoprotein originally identified for its expression on most acute lymphoblastic leukemias (ALL). Subsequently, CD10 was shown to be the same molecule as the neutral endopeptidase (NEP), or KII-NA. CD10 is a Zn2+-dependent metallo-peptidase with endothelin, glucagon, gastrin, neurotensin and bradykinin included among its substrates. CD10 is involved in the regulation of chemotactic and inflammatory processes involving neutrophils. In B cells, CD10 regulates stromal cell-dependent B lymphopoiesis and expression has also been reported on mature B cells in germinal centres. In addition to the hematopoietic compartment, other major sites of CD10 expression are the brush border of enterocytes and renal tubules and glomeruli. There is partial blocking of the eBioCB-CALLA and MEM-78 monoclonal antibodies indicating that they recognize similar epitopes. Applications Reported: This eBioCB-CALLA (CB-CALLA) antibody has been reported for use in flow cytometric analysis. Applications Tested: This eBioCB-CALLA (CB-CALLA) antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells. This can be used at 5 μL (0.06 μg) per test. A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL. Cell number should be determine...

CD10, also known as the Common Acute Lymphocytic Leukemia Antigen (CALLA) and neutral endopeptidase (NEP), is a Zn2+-dependent metallo-peptidase with neutral metalloendopeptidase activity. It is a 100 kDa type II transmembrane glycoprotein encoded by a gene that exists in a single copy of greater than 45 kb. The 5' untranslated region of the CD10 gene is alternatively spliced, resulting in four separate mRNA transcripts, although the coding region remains unaffected by alternative splicing. CD10 is involved in the regulation of chemotactic and inflammatory processes involving neutrophils and plays a role in stromal cell-dependent B lymphopoiesis. It is expressed on immature B cells in adult bone marrow, mature B cells in germinal centers, and cells from patients with chronic myelocytic leukemia (CML). Additionally, CD10 is present on the cells of lymphoblastic, Burkitt's, and follicular germinal center lymphomas. Beyond the hematopoietic compartment, CD10 is highly expressed on the brush border of enterocytes and renal tubules and glomeruli, as well as on breast myoepithelial cells, bile canaliculi, and fibroblasts. CD10 cleaves peptides at the amino side of hydrophobic residues, inactivating several biologically active peptides, including endothelin, glucagon, gastrin, neurotensin, bradykinin, enkephalins, substance P, oxytocin, and others. Diseases associated with CD10 dysfunction include spinocerebellar ataxia 43 and Charcot-Marie Tooth Disease, highlighting its significance in both normal physiological processes and disease states.
