Proteomics Karolinska (PK/KI)

PK/KI is the proteomics core facility at KI located at the department of Department of Medical Biochemistry and Biophysics. We provide services using best available proteomics techniques and methods with focus on label-free quantitative proteomics.


Our main applications:
  • Large scale quantitative proteomics experiment.
  • Accurate molecular mass determination of e.g. peptides and small proteins.
  • Detection of posttranslational modification and their localization on the amino acid sequence.
  • General protein identification and quantitation from different sources.
