Ectonucleotide pyrophosphatase/phosphodiesterase family member 3; E-NPP 3; NPP3; Alkaline phosphodiesterase I ; Dinucleoside polyphosphatase ; Nucleotide diphosphatase; Nucleotide pyrophosphatase ; Phosphodiesterase I beta; Phosphodiesterase I/nucleotide pyrophosphatase 3; CD203c
Reconstitution
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Tag

Relevance
Hydrolase that metabolizes extracellular nucleotides, including ATP, GTP, UTP and CTP.<br />Limits mast cells and basophils response during inflammation and during the chronic phases of allergic responses by eliminating extracellular ATP, a signaling molecule activating these cells in an autocrine manner. Metabolizes extracellular ATP in the lumen of the small intestine, and thereby prevents ATP-induced apoptosis of intestinal plasmacytoid dendritic cells.<br />Has a broad specificity and can also hydrolyze UDP-GlcNAc into UMP and GlcNAc-1-phosphate and potentially several other intracellular nucleotide sugars, including UDP-GalNAc, CMP-NeuAc, GDP-Fuc, and UDP-GlcA. Thereby, could modulate glycan biosynthesis and protein glycosylation.<br />Can hydrolyze extracellular dinucleoside polyphosphates, including the vasoactive adenosine polyphosphates as well.<br />In addition, displays an alkaline phosphodiesterase activity in vitro.

Form
Lyophilized powder
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
Lyophilized from a 0.2 um filtered 20 mM Tris-HCl, 0.5 M NaCl, 6% Trehalose, pH 8.0
Purity
Greater than 95% as determined by SDS-PAGE.
Storage
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. <br />Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
