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.

Sucrose is used as a stabilizer.

It is stable in liquid form below 50°C (Fig.4) and remains stable at 37°C for at least three weeks (Fig.5). In powder form, it remains stable at 30°C

The optimal pH is 7.0–9.0, and the optimal temperature is 45°C.

The molecular weight is approximately 80 kDa (gel filtration), and it exhibits a dimeric structure composed of subunits of 48 kDa each (SDS-PAGE).

It is useful for the determination of creatinine and creatine in clinical analysis.
