Description
The 14.27 monoclonal antibody specifically recognizes CD38, which is also known as ADP-ribosyl cyclase/cyclic ADP-ribose hydrolase 1 or ADP-ribosyl cyclase 1 (ADPRC 1). CD38 a 45 kDa type II transmembrane glycoprotein that is encoded by Cd38 (CD38 molecule). CD38 is variably expressed on early hematopoietic precursors and leucocytes including immature and mature B cells as well as thymocytes, T cells, NK cells, monocytes, and macrophages. It is also expressed on non-hematopoietic cells such as epithelial cells, astrocytes, hepatic stellate cells (HSCs), and Kupffer cells. CD38 catalyzes the synthesis and hydrolysis of cyclic adenosine diphosphate ribose (cADPR) and nicotinic acid adenine dinucleotide phosphate (NAADP) which can function as secondary messengers involved in calcium mobilization. The 14.27 antibody can reportedly stimulate increased cytosolic Ca2+ levels, IL-6 production and increased expression of the adhesion molecules, VCAM-1, N-CAM, and ICAM-1 by HSCs.
BD® CompBeads can be used as surrogates to assess fluorescence spillover (compensation). When fluorochrome conjugated antibodies are bound to BD® CompBeads, they have spectral properties very similar to cells. However, for some fluorochromes there can be small differences in spectral emissions compared to cells, resulting in spillover values that differ when compared to biological controls. It is strongly recommended that when using a reagent for the first time, users compare the spillover on cell and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.
The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to the dye under optimum conditions and unreacted dye was removed. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.
