CD38 Recombinant Antibody [HB7] (OAAV00092)

2'-phospho-ADP-ribosyl cyclase;2'-phospho-ADP-ribosyl cyclase/2'-phospho-cyclic-ADP-ribose transferase;2'-phospho-cyclic-ADP-ribose transferase; ADPRC 1; ADPRC1; ADP-ribosyl cyclase 1; ADP-ribosyl cyclase/cyclic ADP-ribose hydrolase 1; CD38 antigen (p45) ; cluster of differentiation 38; cyclic ADP-ribose hydrolase 1; ecto-nicotinamide adenine dinucleotide glycohydrolase; NAD (+) nucleosidase; T10.

Viable cells (1 x 10E7) of the human cell line, BJAB (Human Burkitt lymphoma B cell line), which was were injected intraperitoneally into 8-week-old BALB/c mice.

Synthesizes the second messagers cyclic ADP-ribose and nicotinate-adenine dinucleotide phosphate, the former a second messenger for glucose-induced insulin secretion. Also has cADPr hydrolase activity. Also moonlights as a receptor in cells of the immune system.

This antibody binds to an epitope between amino acids 273-285 of human CD38, an approximately 45 kDa type II transmembrane protein, expressed on essentially all pre-B lymphocytes, plasma cells, and thymocytes. Also present on activated T lymphocytes, natural killer (NK) lymphocytes, myeloblasts, and erythroblasts. Bimodally expressed during B cell development, modulating from high in immature cells to low in intermediate ones and back to high on mature B cells. This antibody competes with clone AT13/5
