Abstract

Certain aspects of this disclosure are generally related to methods for separating a plurality of particles from a fluid. In some embodiments, the fluid comprises one or more polypeptides and a plurality of particles. In some embodiments, the method comprises at least partially denaturing a polypeptide in the fluid to form a denatured polypeptide. In some embodiments, the method comprises separating a mixture of the denatured polypeptide and at least 10% of a plurality of particles from the fluid. Without wishing to be bound by any particular theory, the denaturation of the polypeptide in the fluid may allow for some of the plurality of particles to associate with the denatured polypeptide, and/or agglomerate with the denatured polypeptide. The mixture comprising the denatured polypeptide and the plurality of particles may settle (e.g., precipitate) in the fluid and may therefore be separated from the fluid.
