CD10, Alexa Fluor 700, clone: eBioCB-CALLA (CB-CALLA), eBioscience™

Description

CD10 (neutral endopeptidase - NEP, common acute lymphocytic leukemia antigen - CALLA, membrane metallo-endopeptidase - MME, enkefalinase) is a 100-kDa cell surface zinc metalloprotease cleaving peptide bonds on the N-terminus of hydrophobic amino acids and inactivating multiple physiologically active peptids. CD10 is expressed on various normal cell types, including lymphoid precursor cells, germinal center B lymhocytes, and some epithelial cells, and its expression level serves as a marker for diagnostics of many carcinomas. CD10 is also a differentiation antigen for early B-lymphoid progenitors in the B-cell differentiation pathway and has a key role in regulation of growth, differentiation and signal transduction of many cellular systems.

Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. Alexa Fluor® 700 emits at 723 nm and can be excited with the red laser (633 nm). Most instruments will require a 685 LP mirror and 710/20 filter. Please make sure that your instrument is capable of detecting this fluorochrome. Excitation: 633-647 nm; Emission: 723 nm; Laser: Red Laser. Filtration: 0.2 μm post-manufacturing filtered. CD10 (Common Acute Lymphocytic Leukemia Antigen ,CALLA), is a cell surface enzyme with neutral metalloendopeptidase activity which inactivates a variety of biologically active peptides. CD10 is expressed on the cells of lymphoblastic, Burkitt′s, and follicular germinal center lymphomas, immature B cells with in adult bone marrow and on cells from patients with chronic myelocytic leukemia (CML). CD10 is also present on breast myoepithelial cells, bile canaliculi, fibroblasts, with especially high expression on the brush border of kidney and gut epithelial cells. CD10 is a neutral endopeptidase that cleaves peptides at the amino side of hydrophobic residues and inactivates several peptide hormones including glucagon, enkephalins, substance P, neurotensin, oxytocin, and bradykinin. Further, CD10 is a 100 kDa type II transmembrane glycoprotein 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 and the coding region is not affected by alternative splicing. Diseases associated with CD10 dysfunction include spinocerebellar ataxia 43 and Charcot-Marie tooth Disease.
