Protein sequencing is a method that typically utilizes mass spectrometry (MS) to determine the amino acid code of a protein1. Prior to the development of mass spectrometry, Edman degradation, a method involving the stepwise degradation of peptides to derive the order of amino acids, was the mainstream approach. Nowadays, mass spectrometry is favored due to its ease of use and high throughput capabilities, though Edman degradation is still employed for specific applications in which the technique is well suited.
Antibodies are used in a variety of ways in academia and industry, from tools to therapeutics. Because antibodies are produced using live processes, which are naturally error-prone, validation is required from time to time. Furthermore, to develop biological therapeutics, the protein sequence must be confirmed as part of the regulatory process.
The protein sequence is key to understanding the function of a protein target and is critical to therapeutic and diagnostic development. This is particularly important for antibodies whose code diversity and glycosylation impact both function, and stability.
To develop robust mAb biologics, it is vital to fully characterize the protein, including its primary sequence, mutations, and important post-translational modifications
