Biotinylated Human CD38 Protein, Fc, Avitag™ (MALS verified)

• Background:

  CD antigen CD38 is also known as ADP-ribosyl cyclase 1, which belongs to the ADP-ribosyl cyclase family. CD38 is expressed at high levels in pancreas, liver, kidney, brain, testis, ovary, placenta, malignant lymphoma and neuroblastoma. CD38 is a multifunctional ectoenzyme that catalyzes the synthesis and hydrolysis of cyclic ADP-ribose (cADPR) from NAD+ to ADP-ribose. These reaction products are essential for the regulation of intracellular Ca2+. The loss of CD38 function is associated with impaired immune responses, metabolic disturbances, and behavioral modifications. The CD38 protein is a marker of cell activation. It has been connected to HIV infection, leukemias, myelomas, solid tumors, type II diabetes mellitus and bone metabolism. CD38 has been used as a prognostic marker in leukemia.

• Description:

  Biotinylated Human CD38, Fc, Avitag (CD8-H82F5) is expressed from human 293 cells (HEK293) . It contains AA Val 43 - Ile 300 (Accession # P28907-1) .

• Specifications:

  This protein carries a human IgG1 Fc tag at the C-terminus, followed by an Avi tag (Avitag™) . The protein has a calculated MW of 58.0 kDa. The protein migrates as 65-75 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
