Mass spectrometry is a powerful analytical technique that measures the mass of ionized molecules for identification and quantization in simple and complex mixtures.
We offer proteomics services to internal and external clients. Our current service offers identification and label-free quantitation of up to up to 8000 proteins in client samples using a standardized proteomics workflow on our timsTOF Pro2 instruments using the Spectronaut software.
We are also open to collaborative research projects that are aligned with the internal focus and expertise of the technology center. Please use the contact form at the top of our RTC page if you would like to discuss possibilities.

Peptide mixtures are separated using C18 reversed phase nanoflow liquid chromatography using the EvoSep One liquid chromatograph. Peptides eluting from the column are measured using data-independent acquisition Parallel Accumulation Serial Fragmentation (dia-PASEF) by the timsTOF Pro2 mass spectrometer.
Data processing is performed in real-time using the Spectronaut search engine (ProteinScape) for fast turnaround time. The customer will receive an MS Excel file with protein identification and label-free quantitation result tables, raw datafiles, and materials & methods documentation.
Results will be sent to customers within 3 weeks after we have received the samples. Please contact us if you plan to use this service and to receive a quote.

To submit samples for proteomics you first need to contact us to register your samples. Please use the contact form at the top of our RTC page if you would like to discuss possibilities.
If needed, a short intake meeting will be scheduled to align services with the customer. Following registration and quotation, you may proceed with sample preparation and schedule an appointment for sample transfer. It is possible to submit either protein extracts or protein digests for proteomics. For available protein extraction protocols or in case of questions, you can contact us as well.
Guidelines for samples
- Samples should not contain any particles or cellular debris.
- Avoid the use of detergents and polymers (e.g. SDS, BRIJ 35, NP40, triton x-100, PEG) if possible. Please inform us when detergents or polymers are required for your sample preparation.
- The customer needs to perform protein quantitation (e.g. using nanodrop or micro bca kit) themselves.
- Recommended protein amount and concentration: at least 10µg protein at a concentration of 0.1-10 µg/µl.
