适用类型
FADGDH-AD is useful for the determination of D-glucose in clinical analysis and continuous glucose monitoring (CGM) meter for diabetes patients. The FADGDH-AD was developed as an oxygen-insensitive alternative to Glucose oxidase (GOD) with its high stability for the applications such as bioelectrodes in glucose sensing device and glucose enzymatic fuel cells.
