Webb11 apr. 2024 · Acetone precipitation was then performed on the collected organic phases to precipitate the purified proteins. To extract the protein-bound RNAs, the interface was resuspended in 200 μl of PBR buffer (1%SDS, 30 mM Tris–HCl (pH 8), 10 mM EDTA), and the protein component was digested by the addition of 18 U of RNA-grade Proteinase K … Salting out Salting out is the most common method used to precipitate a protein. Addition of a neutral salt, such as ammonium sulfate, compresses the solvation layer and increases protein–protein interactions. As the salt concentration of a solution is increased, the charges on the surface of the protein interact with … Visa mer Protein precipitation is widely used in downstream processing of biological products in order to concentrate proteins and purify them from various contaminants.
