CD73 antibody has been tested by ELISA and Western blot analysis to assure specificity and reactivity. Recommended dilution range for Western blot analysis is 1:1,000 ~ 2,000. Recommended starting dilution is 1:1,000.
Anti-human CD73 mAb , is derived from hybridization of mouse FO myeloma cells with spleen cells from BALB/c mice immunized with recombinant human CD73 amino acids 27-252 purified from E. coli.
Ecto-5-prime-nucleotidase (5-prime-ribonucleotide phosphohydrolase) catalyzes the conversion of purine 5-prime mononucleotides to nucleosides, the preferred substrate being AMP at a neutral pH. CD73, which consists of a dimer of 2 identical 70kDa subunits, is bound by a glycosyl phosphatidyl inositol linkage to the external face of the plasma membrane. CD73 is used as a marker of lymphocyte differentiation. Consequently, a deficiency of NT5 occurs in a variety of immunodeficiency diseases. Additional 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.
