So we cross out the three zeros and we get 125 divided by one. And that leaves us with 125. Now, what about the purification level? The purification level is 125 divided by ten and that gives us 12.5. And so we see that this extracted sample following this salting out procedure and on exchange chromatography, this extracted sample of proteins is 12.5 times more pure than our original sample. And that is a good thing.
