A reduced dinucleotide, preferably nicotinamide adenine dinucleotide (NADH) is stabilized, in an aqueous base liquid containing propylene glycol boric acid and a buffer capable of buffering within a pH range of 8-11. The stabilized liquid contains greater than 50% (v/v) water. The remaining volume contains propylene glycol which has been chemically treated to remove oxidants. This reagent may be used by itself or in conjunction with an assay reagent system for use in the clinical laboratory.
