97C5 recognizes human CD10, the human common acute lymphoblastic leukemia antigen (CALLA). CD10 is a 100 kDa cell surface molecule identical to human membrane-associated neutral endopeptidase (NEP) and also known as neprilysin or enkephalinase. Human CD10 is expressed on a wide variety of normal and neoplastic cell types from different tissues including neural and hematopoietic cells. It is expressed on pre– and pro–B cells and is involved in B cell development and differentiation. The antigen is also present on mature neutrophils, T cell precursors, and some T cell leukemias/lymphomas. Furthermore, CD10 is expressed on neoplastic cells of several B lymphoid leukemias/lymphomas.
An antibody, specific receptor protein, ligand, nucleic acid sequence (e.g., primer, probe) or similar reagent, which through specific binding or chemical reaction with an intended target, is used to identify or quantify a chemical substance in a biological specimen for the development of a laboratory developed test (LDT) or commercial in vitro diagnostic medical device (IVD). Commonly referred to as an analyte specific reagent (ASR), it is neither labelled with instructions for use nor diagnostic or performance claims.
