So we have eight processes. We have dialysis. Now, the thing about dialysis is it doesn't actually allow us to separate different proteins, but what it allows us to do is it allows us to separate the proteins from other small molecules and ions by using a semipermeable membrane. Now, salting out is basically the process by which we separate our protein based on its ability to form a precipitate at a specific type of salt concentration. So, for example, one protein can precipitate at a concentration of salt, let's say around one molar, but another one will form a precipitate only at two molar and so forth. So we can use salting out to basically separate different proteins.
