But other times, they make their way around the beads, and so they will be found somewhere in the middle as compared to the green, which will be found at the top. Now, these large proteins essentially never make their way into those beads because they simply cannot fit into the internal volume of those beads. And so what happens is they will emerge first, they will be found at the bottom relative to these two other proteins. So we have the protein, this protein number one. We have this protein number two. And we have here this protein number three.
