And so now we can dump that out because we don't want to actually use this in our experiment, remember, our focus was basically to isolate protein number one and not protein number two or protein number three. Okay? And finally, in the last step, so the question is, how do we get that protein number one out of that column? 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.
