Proteomics Biomedicum

Proteomics Biomedicum (previously Proteomics Karolinska PK/KI) is the proteomics core facility at KI located at the Department of Medical Biochemistry and Biophysics. We provide services using best available proteomics techniques and methods with focus on quantitative proteomics, both label-free and multiplexed TMT-labeling.

Services

  • Large scale quantitative proteomics experiments
  • Single cell proteomics by mass spectrometry
  • Accurate molecular mass determination of peptides and small proteins.
  • Detection of posttranslational modification and their localization on the amino acid sequence.
  • General protein identification in gel and solution

Proteomic analysis of SARS-CoV2 infected human cells

We have recently completed a proteomic analysis with human cells infected with SARS-CoV-2 generating unique data quantifying >7000 human and 5 viral proteins in a time series. The proteomic results were interplayed with transcriptomic data resulting in a novel insight to how SARS-CoV-2 can alter the cellular processes.

The manuscript is currently under review but the proteomic data is already published
