But what happens to this one? Well, nothing, because it requires 2.4 molar to actually precipitate. And so while this one will crystallize, the albumin will not crystallize. And what we can do now is apply another method, another technique that we're going to focus on in the next lecture, known as dialysis. And if we apply dialysis to this particular case, we can basically separate and isolate that fibrinogen from the mixture of this serum albumin. And at that particular point in time, we now have two different beakers.
