Agent for protein precipitation, a method of protein precipitation, a method of protein assay using protein precipitation agent, and a kit for protein assay

摘要

A method of protein precipitation, concentration and removal of non-protein agents from the protein solution wherein the protein solution is treated with a protein-precipitation agent containing an acidic agent, a salt and a precipitate forming agent. After precipitation, the protein precipitate is washed with a water miscible organic solvent agent to remove non-protein agents present in the protein precipitate.
