Due to the high number of peptides, we get sequence information for EVERY peptide bond in the antibody. Typically, 20-70 different MS/MS spectra are generated for each amino acid (AA) position. Hence, even the hardest sequences of proline and arginine-rich peptides can be resolved. As the order of all amino acids is clear, there is no need for time-consuming techniques like Edman sequencing. http://www.creative-biolabs.com/next-generation-antibody-sequencing.html
