Description

Recombinant Protein

It is recommended that the protein be aliquoted for optimal storage. It is recommended that sterile water (400 μL) be added to the vial to prepare a stock solution of 1.25 mg/mL. Concentration is measured by UV.

CD38 is a multifunctional ectoenzyme and type II transmembrane glycoprotein involved in various cellular processes. It catalyzes the conversion of NAD into secondary messengers such as nicotinic acid adenine dinucleotide phosphate (NAADP) and cyclic ADP-ribose (cADPR). CD38 plays a crucial role in B cell development, with expression levels fluctuating from high in immature cells to low in intermediate ones, and back to high in mature B cells. It is also present in a variety of tissues and hematopoietic cells, including T cells, NK cells, and monocytes, and is used to phenotype leukemias and monitor HIV-1 progression. The CD34+CD38- population is considered to define the most pluripotent hematopoietic stem cells. In addition to its surface expression, CD38 has been identified in the nucleus, where it may regulate calcium levels. It functions as a multi-catalytic ectoenzyme, serving roles as an ADP-ribosyl cyclase, cyclic ADP-ribose hydrolase, and possibly NAD+ glycohydrolase, or as a cell surface receptor. CD38 is involved in the activation, proliferation, and differentiation of mature lymphocytes and mediates apoptosis of myeloid and lymphoid progenitor cells. It also participates in cell adhesion, signal transduction, and calcium signaling. Antibodies to CD38 are valuable for subtyping lymphomas and leukemias, detecting plasma cells (such as in myelomas), and marking activated B and T cells. CD38 is expressed at high levels in the pancreas, liver, kidney, malignant lymphoma, and neuroblastoma. Dysfunctions in CD38 are associated with diseases like chronic lymphocytic leukemia and Richter's Syndrome.
