Method for Detecting and/or Removing Protein and/or Peptide Comprising a Cross-Beta Structure From an Aqueous Solution Comprising a Protein

摘要

The invention relates to the field of aqueous solutions comprising a protein. More specifically, the invention relates to the detection and/or removal of conformationally altered proteins and/or peptides comprising a cross-β structure from an aqueous solution comprising a protein. The invention provides methods for detecting and/or removing proteins and/or peptides comprising a cross-β structure from an aqueous solution comprising a protein, said method comprising contacting said aqueous solution comprising a protein with at least one cross-β structure-binding compound resulting in a bound protein or peptide with cross-β structure. The invention further provides a aqueous solution comprising a protein obtainable by a method of the invention, and a kit for carrying out the methods of the invention.
