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.

Raffinose is used as a stabilizer.

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

The optimal pH is 6.0–8.0, and the optimal temperature is 40–50°C.

The molecular weight is approximately 115 kDa (gel filtration), and it exhibits a dimeric structure composed of subunits of 70 kDa each.

It is useful for the determination of L-glutamate.
