Introduction to the facility

Experimental sample types range from protein gel bands through affinity-purified proteins with interacting partners to complex cell lysates. The lab has expertise in sample preparation, digestion and clean-up prior to mass spectrometry and can advise as necessary on these important aspects of experimental design. In addition to bottom-up discovery-type experiments, the facility has the capability for quantitative proteomic experiments using peptide label (iTRAQ) or label-free (SWATH) approaches.

Overview

  • Tims cartridge accumulates and separates eluting peptides according to collisional cross-sectional area.​
  • PASEF technology enables ion accumulation and fractionation in parallel.​
  • Ion mobility data provides an additional analytical dimension for increased confidence in IDs.

Specification

  • Fast data acquisition – MS/MS spectrum collection at up to 120 Hz.​
  • Greater depth of coverage of complex samples, with significantly enhanced capability for detection of  low abundance proteins and post-translational modifications.

Protein identification

  • Modified methods available for low protein-abundance samples ~2500 protein IDs 12.5ng.​
  • Label-free quantification (LFQ) available using spectral libraries generated in-house and library-free options are being investigated.
