C-6His

Greater than 95% as determined by reducing SDS-PAGE.

Less than 0.1 ng/μg (1 IEU/μg) as determined by LAL test.

Measured by its ability to hydrolyze the 5’-phosphate group from the substrate adenosine-5’-monophosphate (AMP). The specific activity is 8000-24000 pmol/min/μg.

CD73 is a glycosyl phosphatidylinositol (GPI) anchored membrane protein that belongs to the 5'-nucleotidase family. CD73 is an ecto 5'Nucleotidase expressed by most cell types. CD73 hydrolyzes extracellular nucleotides into membrane permeable nucleosides. CD73 is one of several enzymes responsible for the production of extracellular adenosine, a signaling molecule that is involved in responses to inflammation and tissue injury. CD73 is a lymphocyte maturation marker that has functions independent of its catalytic activity. CD73 is also a regulator of leukocyte extravasation, a function that requires its 5'Nucleotidase activity. Defects in NT5E are the cause of calcification of joints and arteries (CAJA). The recombinant CD73 lacking GPI anchor is secreted as a monomer.
