Characterizing protein impurities is a key requirement of ICH Q6B.

 

We can search for:

  • Product-related impurities

which are basically types of protein modification. Examples are deamidation or oxidation. We analyze these with a combination of 2D gel electrophoresis, high performance liquid chromatography (HPLC) and peptide mapping.

  • Process-related impurities,

such as host cell proteins, which we can detect using ELISA, 2D gel electrophoresis, western blotting or mass spectrometry.
