  • Method for removing endotoxins from protein solutions
    Publication number: 20040198957
    Abstract: A method for removing endotoxin contaminants from protein solutions using hydrophobic charge induction chromatography sorbents. The methods comprise adjusting the ph of a protein solution to a pH of from about 8.0 to about 9.0, binding the protein to a hydrophobic charge induction chromatography sorbent; and eluting the protein from the sorbent using an elution buffer having a pH of from about 3.0 about 5.0. The method is particularly useful for removing endotoxin contaminants from antibody compositions.
