The Thermo Scientific™ HeavyPeptide AQUA FasTrak Service is a 2-step approach to help accelerate targeted assay development and absolute quantitation by selected reaction monitoring (SRM) within a controlled budget. While typical quantitative proteomics workflows employ a peptide identification step followed by target quantitation using purified HeavyPeptides, the HeavyPeptide FasTrack Service combines both steps for a rapid, precise, and more cost-effective workflow.

  • Efficient—no need to resynthesize selected peptides for target quantitation
  • Accurate—concentration precision for reproducible results
  • Sensitive—enables the absolute quantification of low-abundance proteins
  • Consistent—peptides from one synthesis reaction used for both assay development and target quantitation
