Webb31 okt. 2007 · Fluctuations in protein concentration are assumed to be the driving force for protein crystallization. The term ‘nucleus’ refers to the smallest aggregate that is capable of spontaneous growth. In a typical protein crystallization experiment, crystals grow from a supersaturated aqueous solution by a process that involves homogenous nucleation. Webb20 jan. 2024 · Once the protein concentration is sufficiently high, nucleation may occur. If the protein concentration is too high, however, it will form an amorphous precipitate.
