Introduction
Ecto-5-prime-nucleotidase (5-prime-ribonucleotide phosphohydrolase) catalyzes the conversion of purine 5-prime mononucleotides to nucleosides, with AMP being the preferred substrate at a neutral pH. CD73, a dimer composed of two identical 70kDa subunits, is anchored to the external surface of the plasma membrane via a glycosyl phosphatidyl inositol linkage. Serving as a marker for lymphocyte differentiation, CD73 deficiency is observed in various immunodeficiency disorders. Other forms of 5-prime nucleotidase, present in the cytoplasm and lysosomes, can be differentiated from ecto-NT5 based on substrate affinities, divalent magnesium ion requirement, ATP activation, and inorganic phosphate inhibition.

Formulation
Concentration: 1mg/ml. Formulation: PBS (pH 7.4) with 0.1% Sodium Azide.
Storage Procedures
For storage up to 1 month, maintain at 4°C. For extended periods, store at -20°C. Avoid repeated freeze-thaw cycles.

Applications
CD73 antibody has undergone testing via ELISA and Western blot analysis to confirm its specificity and reactivity. However, due to variations in applications, it's recommended to titrate the reagent for each experiment to achieve optimal results. Suggested dilution range for Western blot analysis: 1:1,000 to 1:2,000. Initial dilution recommendation: 1:1,000.
