So notice that this distribution of bands consists of less bands than before. And what that basically tells us is, as we go from A to B, we decrease the number of proteins inside that mixture that we actually don't want. And so that means it's a good thing, because what that means is we're purifying our protein mixture. 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.
