Peptide mapping is today the method of choice for the characterisation of therapeutic proteins, and is one of the analytical techniques required by ICH guidance Q6B. Either for characterisation or routine testing, it provides a significant amount of data from primary sequence to post-translational modifications. It can be used for early characterisation, release tests or stability studies. With the advent of mass spectrometry as a routine technique in many analytical labs, the power of peptide mapping is even greater.

Thanks to state-of-the-art hardware and software, Quality Assistance is able to provide you with customised solutions for peptide mapping analyses throughout the development of your product, from characterisation studies to batch release and stability testing.
