LAESI® DP-1000 >> LAESI-Based Services

Direct Ionization Mass Spectrometry Analysis Using Protea LAESI DP-1000 System
Protea can now provide direct identification and characterization of biological samples through its proprietary LAESI DP-1000 System interfaced with ion trap technology or ion mobility TOF.

All LAESI-MS Bianalytical Services are reported through a secure, interactive online portal, where you will receive email notifications upon sample receipt, processing stage, and final data report creation.

Services are available for:
  • Profiling biological tissues
  • Profiling living cells/colonies
  • TLC plate separation profiling
  • Direct analysis of biological fluids
  • Real time redox reaction monitoring
  • Material characterization

LAESI, or Laser Ablation Electrospray Ionization is a technique used to profile the spatial distribution of metabolites, lipids, peptides, proteins, and other biomolecules in a wide variety of sample types under ambient conditions with minimal sample handling. Detailed reports include publication quality images and standard MS datasets.
