And if we go to the following table, these values should tell us exactly that. So remember, as we are purifying, the specific activity should increase, and that should increase the purification level. So these two quantities compared to these should actually increase. So let's see if that's true. So to calculate the specific activity we take the enzyme activity of that particular sample divided by the total protein once again of that particular sample. So we get 175 divided by five because these three zeros cancel out and we get a value of 35.
