DIA-NN 2.5: a new era of deep proteomics

  • Transformative sensitivity gains, with up to 70% more proteins identified.
  • Advanced capabilities towards statistical analysis and biological interpretation.
  • Interactive visualisation at all levels: from biological pathways and their associated proteins to individual peptides and fragment ion XICs.

Fast and Sensitive Immunopeptidomics

Reanalysis of HLA-I data by Pak et al (PMID: 33845167), where authors originally used a 136k peptide DDA-based spectral library. DIA-NN here uses InfinDIA for ultra-fast full-length non-specific digest search, combined with DIA-NN's peptidoform confidence module. Numbers for two cell lines (JY and RA957) are shown.

Biological Insights & Visualisation

DIA-NN 2.5 enables to gain biological insights from the data in minutes, and confirm the findings by examining how each protein, peptide or PTM site is regulated, with convenient visualisation tools.
