This monograph puts together both commonly used and emerging approaches that employ mass spectrometry to evaluate various aspects of biopharmaceutical products ranging from covalent structure and conformational analysis to their quantitation in complex biological matrices. Also considered are various approaches used for the purity assessment of biopharmaceutical products and the comparability\/biosimilarity studies. While the focus is on protein therapeutics, other biopharmaceutical products are also covered, including oligonucleotide-based drugs and gene therapy products.
