Because the problem now is these proteins are bound to the beads found in that column. So in this particular case, what we can basically do is we can create a solution of glucose, and that glucose is essentially not bound to anything in that solution. So this is our glucose solution, and we wash that column down with the glucose solution. So what will happen is the glucose that is free to move in that solution will now compete for that active side found on that enzyme, enzyme number one, and it will outcompete that glucose that is bound onto the beads. And so once that glucose replaces the glucose that was bounced, the beads, that protein that was initially bounced, the bead, will essentially move away from that bead and will continue moving down our column because now it contains the active side that is filled with that glucose. And in this manner, we can basically wait until it goes all the way to the bottom.
