ProteomicsDe novo sequencing of antibody light chain proteoforms from patients with multiple myeloma
In multiple myeloma diseases, monoclonal immunoglobulin light chains (LCs) are abundantly produced, with as a consequence in some cases the formation of deposits affecting various organs, such as kidney, while in other cases to remain soluble up to concentrations of several g.L-1 in plasma. The exac...

ProteomicsApplication of de novo sequencing to large-scale complex proteomics datasets
Dependent on concise, pre-defined protein sequence databases, traditional search algorithms perform poorly when analyzing mass spectra derived from wholly uncharacterized protein products. Conversely, de novo peptide sequencing algorithms can interpret mass spectra without relying on reference datab...

ProteomicsIdentification of Unknown Biological Toxin Protein Using Mass Spectrometry: A Case Study on De Novo Sequencing of Ricin
Currently, the genomes of many toxin proteins remain unsequenced. Characterizing these toxin proteins and their active peptide segments is crucial for the development of detoxification agents and for discovering proteins with potential therapeutic applications. Existing methods for identifying and d...

ProteomicsCombining de novo peptide sequencing algorithms, a synergistic approach to boost both identifications and confidence in bottom-up proteomics
Complex MS-based proteomics datasets are usually analyzed by protein database-searches. While this approach performs considerably well for sequenced organisms, direct inference of peptide sequences from tandem mass spectra, i.e. de novo peptide sequencing, oftentimes is the only way to obtain inform...

ProteomicsNovoBoard: a comprehensive framework for evaluating the false discovery rate and accuracy of de novo peptide sequencing
De novo peptide sequencing is a fundamental research area in mass spectrometry (MS) based proteomics. However, those methods have often been evaluated using a couple of simple metrics that do not fully reflect their overall performance. Moreover, there has not been an established method to estimate ...

ProteomicsNext Generation Protein Sequencing
NGPS is a method for de-novo, full-length protein sequencing in high throughput. The method is based on cleavage of the protein at semi-random sites by microwave-assisted acid hydrolysis (MAAH), enrichment of LC-MS/MS amenable peptides from the hydrolysate by solid-phase-extraction, LC-MS/MS analysi...

ProteomicsTemplate-based assembly of proteomic short reads for de novo antibody sequencing and repertoire profiling
We developed a software package STITCH (https://github.com/snijderlab/stitch) to perform template-based assembly of de novo peptide reads from antibody samples. As a test case we generated de novo peptide reads from protein G purified whole IgG from COVID-19 patients.
