The solubility of this enzyme is tested on the finished product at 1 mL per vial in water. The 100-unit package size will be readily soluble in 1 mL, however, the number of actual units per vial should be reviewed in the lot-specific certificate of analysis. The vial content is typically greater than 100 units. The reconstitution volume would have to be adjusted accordingly in order to achieve a 100 unit per milliliter concentration.

General description
Apyrase, also known as ATP-diphosphohydrolase, is expressed in wide variety of plant and animal tissues. The commercially accessible apyrase enzyme is isolated from potato tubers.
Biochem/physiol Actions
Apyrase hydrolyses the phosphoanhydride bonds of nucleoside tri- and di-phosphates in the presence of divalent cations. It has wide substrate specificity for nucleotides. This property of the enzyme makes it suitable for different biotechnical applications, including DNA sequencing and platelet-aggregation inhibition.
