| Zusammenfassung: | The present invention relates to a process for (pre)treating affinity chromatography matrices, preferably protein A matrices, with at least one surfactant for reducing ligand leakage. By treating the affinity chromatography matrix according to the invention it is possible to achieve an affinity chromatography matrix of constant quality in terms of ligand leakage, which is an important prerequisite for its suitability or use in biopharmaceutical processes. The present invention further relates to methods for determining the ligand leakage. |
