STABILIZED LIQUID ENZYME COMPOSITION FOR GLUCOSE DETERMINATION

摘要

1012-184/5221 A homogeneous liquid enzyme reagent for the quantitative determination of glucose comprises the enzymes hexokinase and glucose-6-phosphate dehydrogenase in a solution of glycerol (30 v/v) in water, and a stabilizer system comprising a heavy metal ion chelating agent. Preferably the stabilizers also comprise an antioxidant and a microbio-control agent. The stabilizers are in sufficient amounts such that the enzyme reagent has a shelf life of at least about two years when stored at a temperature of from 2 to 8.degree.C.
