REA263 recognizes the CD13 antigen, a 150–170 kDa type II transmembrane glycoprotein, which is also known as aminopeptidase N or gp150. CD13 is expressed on granulocytes, myeloid progenitors, endothelial cells, epithelial cells, and subset of granular lymphoid cells. It is also broadly expressed in other tissues such as kidney proximal tubules, intestine, and placenta. CD13 is an enzyme that is used as a biomarker to detect damage to the kidneys, and that may be used to help diagnose certain kidney disorders. It also serves as a receptor for one strain of human coronavirus that is an important cause of upper respiratory tract infections. Defects in CD13 appear to be a cause of various types of leukemia or lymphoma. Additional information: Clone REA263 displays negligible binding to Fc receptors.
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.
