Workflows (50)
- Anti-OX40L mAb de novo sequencing (2006): Full-length de novo sequencing of a monoclonal antibody raised against OX40 ligand, from overlapping proteolytic and chemical digests read by mass spectrometry and cross-checked by Edman degradation.
- Automated mAb de novo (Bandeira SPS) (2008): Landmark Nat Biotech 2008 paper by Bandeira, Pham, Pevzner, Arnott & Lill: applies Shotgun Protein Sequencing (SPS), that is MS/MS spectral assembly, end-to-end to a monoclonal antibody, recovering both chains without any prior sequence.
- Camelid VHH top-down sequencing (2010): Determines the primary structure of a 13.6 kDa camelid single heavy chain antibody by MALDI-TOF/TOF top-down analysis, recovering most of the sequence from the intact protein rather than from peptides.
- ABRF-PSRG 2010 antibody top-down de novo sequencing (2010): Sequenced the N- and C-terminal regions of both chains of the ABRF-PSRG 2010 study antibody by MALDI in-source decay top-down de novo sequencing.
- Immunoglobulin peptide biomarker profiling (2010): Immunoglobulin peptides themselves used as biomarkers of an immune response, rather than the antigens they bind. Rats were immunised with one of two purified antigens and immunoglobulins from pre- and post-immune sera were profiled by nano-LC on an LTQ-Orbitrap with top-5 data-dependent fragmentation, giving 684 peptides differentially present between the treatment groups and cluster separation of the two. Sequences were obtained for 44% of spectral features by combining Mascot database search with de novo sequencing in PEAKS Studio 5.1, merged in Progenesis, which keeps the best-scoring sequence per feature. The authors state the de novo half was essential, because immunoglobulins are poorly represented in sequence databases. The shared peptides found across animals indicate that repertoire development is not fully random but under selection pressure favouring the best-binding sequences.
- CDR peptide biomarker sequencing (2011): Tests detection of specific antibody CDR peptides in serum IgG backgrounds by Orbitrap MS, de novo sequencing half of the detectable adalimumab CDR peptides at attomole levels.

- Polyclonal IgG neutralizing antibody discovery (2024): Sequencing the circulating antibody repertoire itself rather than the B cells that make it. Human plasma-derived polyclonal IgG is sequenced by combining mass spectrometry with B-cell sequencing, applied to the IgG response to the Moderna Spikevax COVID-19 vaccine. Twelve recombinant antibodies were generated from the natural polyclonal response; six of them, including four derived by de novo protein sequencing, bound at least as well as the original polyclonal antibody, and all six neutralised the target antigen. The argument for the approach is that sequencing peripheral B cells may not represent the complete receptor repertoire, so the circulating IgG pool has to be examined directly. Notable as antibody discovery carried out end to end by a commercial de novo sequencing service.
