Technical Data
5'-Nucleotidase (CD73, CD73 Antigen, Ecto-5'nucleotidase, 5'-NT, eN, eNT, NT5, NT5E, NTE, Purine 5 Prime Nucleotidase) discontinued see N7100-71A
CD73 (also known as [ecto]-5'-nucleotidase/5'-NT) is a variably glycosylated, 69-73kD member of the 5'-nucleotidase family of enzymes. It is expressed on multiple cell types, including vascular endothelium, transitional and nonkeratinized epithelium, cardiomyocytes, small intestine epithelium, FoxP3 Treg lymphocytes, FDCs, and B cells. CD73 hydrolyzes AMP to adenosine and phosphate. This creates diffusible nucleosides necessary for cell homeostasis, and a ligand for cell membrane adenosine receptors. Mature human CD73 is a 523aa GPI-linked protein (aa27-549). It contains a large Zn-dependent nucleotidase catalytic region (aa28-532) and a C-terminal substrate binding site (aa500-506). On the cell surface, it exists as a disulfide-linked homodimer. Two splice variants are reported. One shows a deletion of aa405-454, and a second possesses a 12aa substitution for aa253-574. Over aa1-511, human CD73 shares 88% aa identity with both mouse and rat CD73.

Suitable for use in ELISA and Western Blot. Other applications not tested.

Recommended Dilution:
Western Blot: 1:1,000-1:2,000
Optimal dilutions to be determined by the researcher.

Sp2/0 myeloma cells with spleen cells from Balb/c mice.

Storage and Stability:
May be stored at 4C for short-term only. For long-term storage and to avoid repeated freezing and thawing, add sterile 40-50% glycerol, aliquot and store at -20C. Aliquots are stable for at least 12 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
