Mass spectrometry-based proteomics

Qualitative and quantitative analyses of proteins and proteomes.

Welcome to the mass spectrometry-based proteomics facility at Uppsala University. We are located at the Department of Chemistry-BMC, Analytical Chemistry. We offer tailored proteomic solutions for projects from both academia and industry.

SERVICES

  • Qualitative proteomics. Identification of proteins in complex biological samples.
  • Quantitative proteomics. Label-free and labeling techniques.
  • Body fluid proteomics. E.g. cerebrospinal fluid and plasma.
  • Characterization of post-translational modifications. e.g. protein phosphorylation and glycosylation.
  • Proteomics of samples from non-human species. E.g. cats, dogs, plants, bacteria and parasites.
  • Protein identification. From solution and gel spots/bands.
  • Determination of the intact mass of recombinant and native proteins.
  • Immunoprecipitation and identification of target proteins. The facility offers advice on experimental set up for identification of immunoprecipitated and co-immunoprecipitated proteins with MS.
  • In depth characterization of native and recombinant proteins.
  • Protein extraction. Selective extraction of proteins from cells and tissues.
  • Protein separation. 1-D SDS-PAGE Ion chromatography fractionation (SCX, ERLIC)
  • Training services. We provide courses and workshops.
