Protein analysis for testing process-related impurities

Eurofins BioPharma Product Testing network of laboratories offers the testing of all process-related impurities such as residual protein A, DNA or host cell proteins (HCP).

In addition, for product-related substances/impurities, such as post-translational modifications, assays must be used to ensure that all present impurities are below acceptable levels.

All techniques such as ELISA, MSD, chromatography and capillary electrophoresis have been established. Physical and chemical tests, i.e. pH value, appearance, osmolality or particles, complete our package of protein analytical tests.
