The method for preparing the standard solution in this experiment involves the use of a commonly used and widely substrate-specific enzyme to degrade the G6 standard solution followed by separation. However, due to difficulties in purification, the expensive cost of G6 standard solution makes it unable to meet the demands of large-scale production.
