To avoid moisture absorption of the enzyme powder, please allow it to return to room temperature in a sealed state before use. (Recommended conditions: around 25°C, humidity below 55%)

Please store at or below -20°C.

An example of activity measurement: The dehydrogenase activity is assayed in a reaction mixture containing glucose as a substrate, phenazine methosulfate as a mediator and dichlorophenolindophenol (DCIP). The activity is calculated by monitoring the decrease in the absorbance of DCIP at 600 nm.

It shows less than 1% relative activity toward maltose compared to 100% for glucose.

No stabilizers are used.

It is stable in liquid form below 45°C (Fig.4). In powder form, it remains stable at 30°C for at least 20 days (Fig.5).

The optimal pH is 7.0–7.5, and the optimal temperature is 40–50°C.

It exhibits a monomeric structure with a molecular weight of approximately 85 kDa (SDS-PAGE).

It is useful for the determination of blood glucose levels in diabetes diagnosis, with minimal interference from substances such as maltose.
