You are running an enzyme assay that uses the co-enzyme NAD. Its activity is measured in terms of NADH produced. You have obtained the following data: Total volume of assay is 3.0 mL Sample volume is 0.5 mL Absorbance change 7 minutes is 0.350 The molecular extinction coefficient of NADH is 6.22 x 10-3 L/μmol-1/cm-1 and the light path is 1 cm. Calculate the enzyme activity in IU/L.
