Method of Determining Standard Activity Value of Nattokinase

摘要

A method of determining a standard activity value of Nattokinase includes preparing a standard curve with respect to a plurality of Nattokinases having predetermined activity values by calculating corresponding dilution multiples using a standard essay, obtaining a sample curve with respect to an indeterminate Nattokinase by diluting the indeterminate Nattokinase with a plurality sample dilution multiples to calculate corresponding activity values using the standard essay, and determining a standard activity of the indeterminate Nattokinase by comparing the standard curve and the sample curve in a diagram to obtain an intersection.
