Abstract
Compositions and methods are provided that simplify isolation of proteins of interest from serum or plasma. Finely divided silica or a similar lipid/lipoprotein binding solid is used in combination with a protein precipitating agent to generate a solution that includes the protein of interest and that can be applied to chromatography media without resulting in significant fouling of the media. The method is particularly suitable for isolation of immunoglobulin G.
