Human CD73 / NT5E Protein, His Tag (HPLC-verified)

内毒素:
Less than 1.0 EU per μg by the LAL method.

纯度:
>85% as determined by SDS-PAGE.

活性:
Measured by its binding ability in a functional ELISA. Immobilized Human CD73, His Tag (HPLC-verified) (Cat. No. CD3-H52H7) at 2 μg/mL (100 μL/well) can bind Monoclonal Anti-Human CD73 Antibody, Human IgG1 with a linear range of 0.15-5 ng/mL (Routinely tested).

产品背景:
5'-nucleotidase (5'-NT), also known as ecto-5'-nucleotidase or CD73 (cluster of differentiation 73), is an enzyme that is encoded by the NT5E gene. CD73 commonly serves to convert AMP to adenosine. Ecto-5-prime-nucleotidase (5-prime-ribonucleotide phosphohydrolase) catalyzes the conversion at neutral pH of purine 5-prime mononucleotides to nucleosides, the preferred substrate being AMP. Other forms of 5-prime nucleotidase exist in the cytoplasm and lysosomes and can be distinguished from ecto-NT5 by their substrate affinities, requirement for divalent magnesium ion, activation by ATP, and inhibition by inorganic phosphate. Rare allelic variants are associated with a syndrome of adult-onset calcification of joints and arteries (CALJA) affecting the iliac, femoral, and tibial arteries reducing circulation in the legs and the joints of the hands and feet causing pain.

产品描述:
This protein carries a polyhistidine tag at the C-terminus. The protein has a calculated MW of 59.9 kDa. The protein migrates as 30 kDa, 40 kDa and 65 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
