Lactose and EDTA are used as stabilizers.

It is stable in liquid form below 55°C (Fig.4) and remains stable at 37°C for at least one week (Fig.5). In powder form, it remains stable at 30°C for at least four weeks (Fig.6).

The optimal pH is 6.5–7.5, and the optimal temperature is 45–50°C.

The molecular weight is approximately 220 kDa (gel filtration), and it exhibits a dimeric structure composed of subunits of 90 kDa each.

It is useful for the determination of α-amylase and inorganic phosphate in clinical analysis.
