How to calculate enzyme specific activity
Specific activity measures enzyme activity relative to total protein — a purification progress indicator.
How the calculation works
Specific activity = Total activity ÷ Protein mass.
Example
120 units in 8mg protein: 120÷8 = 15 units/mg.
Frequently asked questions
