Sample Profiling & Protein Separation

Highest Standard of Protein Separation Techniques Available

Request More Info

Proteome Sciences uses the very latest and highest standard of protein separation techniques available for profiling of samples prior to biomarker identification. We provide a choice of either a Peptidomics (suitable for small proteins and endogenous peptides) or Proteomics (suitable for larger proteins and fragments) work flow for analysis of samples at our ISO 9001:2008 accredited testing facility.

PS Techniques Available

  • Option of labeled or label-free sample separation
  • Labeling of samples with isotopic or isobaric TMT® tags prior to MS analysis
  • Isobaric protein-level labeling even for plasma
  • Enrichment of membrane and nuclear protein prior to separation
  • Post-translational modification specific chromatography e.g. TiO2 and IMAC
  • 1 and 2-D gel electrophoresis
  • Multi-dimensional liquid chromatography (LC) with micro- and nano-flow
  • Separation protocols for either peptides or proteins
  • Immunoprecipitation for targeted analysis of protein modifications
