Proteomics Core Facility - Thiede

The proteomics group provides service and performs independent research on method development.


Proteomics service offered by the core facility can be found here.

The proteomics facility at IBV is part of the National network of Advanced Proteomics Infrastructure (NAPI).

Research focus

Relevant background information.

Anti-cancer drug action and protein biomarker discovery

A focus of our research of anti-cancer drugs (e.g., Cisplatin, sorafenib, taxol) has been on apoptosis, but we also investigated other processes such as mitotic arrest, ER stress and DNA damage. For this purpose, total cell lysates, subcellular compartments, and posttranslational modifications have been studied.

To consolidate cancer proteomics data, we have created the ApoptoProteomics, Cell Death Proteomics and Cancer Proteomics databases.

Currently, a particular focus of the group is on the proteome, phosphoproteome and glycoproteome analysis of body fluids to discover and validate biomarkers for the diagnosis of prostate cancer.


  • To find protein biomarkers involved in cancer.
  • To investigate proteins involved in processes leading up to apoptosis, including mitotic arrest, DNA damage, and ER stress triggered by different chemotherapeutic drugs.
  • To establish methods for quantitative analysis of posttranslational modifications.
  • To provide proteomics service for customers.

Research achievements

  • We have established and performed proteome analyses using different drugs (e.g., cisplatin, sorafenib, S-trityl-L-cysteine, taxol, and 5-fluorouracil) used or in development for chemotherapy of total cell lysates and subcellular protein assemblies (e.g., proteasome, and lipid rafts).
  • The ApoptoProteomics, Cell Death Proteomics and Cancer Proteomics databases were created for consolidating proteomics data which allows browsing, and analysis of large scale proteome analyses.
  • We have established isobaric peptide termini labeling (IPTL), a novel strategy for isobaric quantification based on the derivatization of peptide termini with complementary isotopically labelled reagents.
  • The software IsobariQ was developed to extract the quantitative information of IPTL data.
  • We have performed quantitative phosphoproteome studies of apoptotic cells.
  • High resolution quantitative proteomics of apoptotic cells was performed by combining SILAC/2-DE/LC-MS.
  • Automatic glycopeptide analysis was implemented using the search engine Mascot.
