Recombinant Human CD157/BST1 Protein (Fc Tag)

C-Fc

Generally, lyophilized proteins are stable for up to 12 months when stored at -20 to -80°C. Reconstituted protein solution can be stored at 4-8°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.

75 kDa

CD38; also called ADP-ribosyl cyclase; is a Type II integral membrane protein with 301 amino acids in length that belongs to the ADP-ribosyl cyclase family.It synthesizes the second messagers cyclic ADP-ribose and nicotinate-adenine dinucleotide phosphate; the former a second messenger for glucose-induced insulin secretion. And also moonlights as a receptor in cells of the immune system. CD38 is expressed in B and T lymphocytes; osteoclasts; and in cardiac; pancreatic; liver and kidney cells. Through its production of cyclic ADP-ribose; CD38 modulates calcium-mediated signal transduction in many types of cells; including neutrophils and pancreatic beta cells.

< 1.0 EU per μg of the protein as determined by the LAL method.

Lyophilized from a 0.2 μm filtered solution of 20mM Tris-HCl, 150mM NaCl, pH 8.0.
Normally 5% - 8% trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the printed manual.

Recombinant Human BST1 is produced by our Mammalian expression system and the target gene encoding Gly29-Lys292 is expressed with a Fc tag at the C-terminus.
