Why add acetone to protein? Proteins are insoluble in acetone (particularly at low temperatures) whilst many small molecules which could interfere with downstream protein work are soluble. By precipitating proteins in this solvent you can remove buffer contaminant and concentrate protein into a pellet which can be redissolved by other solvents.
Why are proteins insoluble in acetone? Acetone is the most commonly used solvent as it promotes protein precipitation and simultaneously dissolves nonpolar molecules like lipids. Acetone prevents dispersion of proteins among water-based solvents causing protein aggregation and precipitation.
What is the advantage of using acetone for precipitation? We typically use three methods for protein precipitation, each have advantages and disadvantages. 1) Acetone is reasonably fast and will precipitate free GlcNAc; 2) Methanol is slow, and does not precipitate GlcNAc; 2) Methanol Chloroform is reasonable fast, but does not work well in the presence of free peptide.
Why do you need to precipitate proteins? The main purpose of protein precipitation is to separate the protein from the solution either to eliminate interferences or to purify them. Depending on the solubility and molecular structure of the protein, the efficacy of various precipitation methods can be different.
