VWR’s Protein Precipitation Kit utilizes a simple trichloroacetic acid (TCA) based method to precipitate proteins in complex mixtures

Only protein in the sample is pelleted, while interfering salts and surfactants remain in the supernatant. A gentle acetone wash removes TCA and co-precipitants allowing the end-user to recover the protein in a small volume of buffer. Kit contains: Protein Precipitation Kit, Solution A, 25 mL, Protein Precipitation Kit, Solution B, 250 mL, and Wash Buffer, 125 mL.
