Clone REA671 recognizes the human CD38 antigen, a single-chain type II transmembrane glycoprotein with enzymatic activity. It is present on the majority of hematopoietic cells, prevalent during early differentiation and activation processes. Terminally differentiated B cells (plasma cells) express CD38 brightly. Furthermore, CD38 is constitutively expressed in several tissues, for example, brain, muscle, and kidney. CD38, a disease marker for human leukemias and myelomas, plays a role in the pathogenesis and outcome of human immunodeficiency virus infection and chronic lymphocytic leukemia, and controls insulin release and also the development of diabetes. Furthermore, it catalyzes the synthesis and hydrolysis of cyclic ADP-ribose (cADPR) from NAD+ to ADP-ribose which is essential for the regulation of intracellular Ca2+. Additional information: Clone REA671 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.
