Abstract
Stable and ready to use liquid reagent for determining the glucose content in blood, comprising a glucose-oxidase free from catalase and a nonionic surface-active agent, such as, for example, the polyoxyethylene derivatives, hydroxypolyethylene ethoxydodecane, the lauryl ether of polyoxyethylene-glycol, as a stabilizer.
Claims7
A ready-to-use aqueous liquid reagent for colorimetric determination of the glucose content in blood, comprising:
- (a) from 9,000 to 40,000 u.i/liter of enzymatically-active glucose oxidase free from catalase;
- and
- (b) from 5 mg/liter to 50 g/liter of a nonionic surface active agent effective to stabilize the liquid reagent.
