We provide expertise and advanced equipment for Proteomics, Metabolomics and Bioenergetics
What services do we offer?
Our lab has state-of-the art technologies for advanced analyses of proteins, metabolites and metabolic activities, and offers collaboration within these areas.
Our work-flows cover steps from sample preparation, data acquisition and data treatment.
The technologies include:
Proteomics:
- Nano-liquid chromatography (LC) coupled to high resolution Mass Spectrometry (nanoLC-MS/MS), for targeted or un-targeted identification and quantification of proteins.
- Luminex for multiplexed XMAP based protein quantification of e.g. inflammatory markers.
Metabolomics:
- Ultra-high performance LC coupled to high resolution Mass Spectrometry, for targeted or un-targeted identification and quantification.
Bioenergetics:
- Seahorse metabolic analyzer XFe96 for quantification of cellular glycolysis and mitochondrial respiration.
The services are open for collaboration projects with actors from:
- Aarhus University
- Other Universities
- Companies
Price
The price of the services will be determined based on project specific factors, like:
- Number of person hours
- Costs of consumables
- Mass spectrometry equipment hours
Booking
The collaboration projects are planned together with Associate Professor Johan Palmfeldt and other relevant experts.
The planning normally starts with an initial meeting followed by written information, and then the practical collaboration.
Guidance and Support
Guidance and support will be provided by the Core Facility, who has established protocols for a wide range of analyses.
The collaborator should specify:
- type and content of the sample to be analyzed
- analytical aim of the project.
Our yearly 4 day PhD courses could be of interest to some collaborators:
Course: Proteomics and protein profiling
The aim is to give the students an overview of proteomics and the study of complex protein samples. The course will cover the theoretical basis and practical methodology of proteomics, as well of the sister technology metabolomics.
Course: Gene to Function
The course covers theoretical background, the experimental methods, and interpretation of results in studies investigating consequences of mutations and molecular disease mechanisms.
Location
Core Facility for Proteomics, Metabolomics and Bioenergetics is located at:
Olof Palmes Alle 49 (ground floor)
8200 Aarhus N
Publications and acknowledgements
In case of publication of data, to which the Core Facility contributed substantially, co-authorships are warranted (Vancouver recommendations). The core facility can aid in the process of manuscript writing and in performing validation experiments, if needed.
