Core Facilities

Core facilities at the Institute of Technology are providing access to sophisticated technologies. Their role is to develop and maintain the knowhow, take care and upgrade the machinery and provide services for scientists and also for wider research community.

In Institute of Technology, there are five core facilities:

Core Facility for Cell Technology

The mission of Core Facility for Cell Technology is to provide high-level technological support for research community, both in academia and industry.

We have the instruments and technical know-how to provide the following services:

There is a fee for our services, please contact the laboratory manager.

First time users must contact Eve Toomsoo ([email protected]) first, training is mandatory before using the machines.

Already know what to do? Please book a time. Booking is currently managed through Microsoft Outlook calendar, accessible to all employees of University of Tartu and PhD students. People outside of university should contact Eve Toomsoo ([email protected]) to secure their access.

Our facility provides mass spectrometry-based analysis of proteomes, proteins, and peptides.

Services:

· Proteome composition analysis: Identifying changes and variations in biological samples using both label-free and labelled approaches (such as SILAC).

· Protein identification and sequencing: Verification of protein identity and sequencing in purified protein preparations, electrophoresis gel bands, and other sources.

· Identification of protein interaction partners: Analysing samples prepared via co-immunoprecipitation, TurboID, and other specialized methodologies.

· Mapping of post-translational modifications: Determination and mapping of modifications such as phosphorylation, ubiquitination, methylation, etc.

· Species origin analysis: Determining the species of origin based on identified proteins (e.g., paleoproteomics and similar fields).

We offer our services to research laboratories at the University of Tartu, elsewhere in Estonia, and abroad, as well as to the private sector.

We suggest reaching out to us during the analysis planning phase to discuss the most appropriate sample preparation and analytical techniques.

Our address:
Proteomics Core Facility,
room #532 Institute of Technology,
University of Tartu,
Nooruse 1,
Tartu 50411,
Estonia

We conduct our analyses using the Q Exactive HF and Q Exactive Plus quadrupole-Orbitrap hybrid mass spectrometers from Thermo Fisher Scientific. Combined with our Dionex Ultimate 3000 RSLC nano-LC liquid chromatographs, these systems create a powerful and modern technical platform for performing qualitative and quantitative proteomics analyses based on liquid chromatography-assisted tandem mass spectrometry (LC-MS/MS).

Along with your samples, please email us a completed order form, the PDF template of which can be downloaded HERE >>

Please download the form to your computer, fill it out in Adobe Acrobat Reader, and save it by adding the date and your name to the filename. For up to ten samples, you can include the sample list at the end of the order form. For more than ten samples, please send the list as a separate Microsoft Excel spreadsheet.

You may deliver the samples in person or mail them to us. For in-person delivery, please contact us in advance to arrange a suitable time. For postal delivery, please use a courier service rather than standard mail.

Cells, tissues, body fluids, protein solutions, and other biological materials should be flash-frozen (e.g., in liquid nitrogen) before shipping. They must be transported frozen, preferably on dry ice (-80°C) or at least at -20°C. Tissue culture cells are best sent as washed, dry cell pellets (centrifuged). Protein bands cut from electrophoresis gels, precipitated or lyophilized proteins, or samples in denaturing buffers should ideally be transported at -20°C (with cold packs), on ice, or with cooling packs. However, these sample types can also withstand room temperature for short periods during transport.

For protein identification from gels, we recommend using Coomassie Brilliant Blue staining. If using a silver staining protocol, please confirm that it is compatible with mass spectrometry. During gel electrophoresis and other sample preparation steps, it is crucial to minimize environmental protein contamination. The primary sources for this are keratins from skin, dust, and bovine serum proteins in cell culture media. To reduce the contamination when preparing samples, please adhere to the following guidelines: always wear fresh gloves, use the freshest, highest-quality reagents available, and ensure all tools and equipment used (containers, electrophoresis plates, combs, etc.) are properly washed and clean.

Note that we do not accept samples containing radioactive proteins or compounds for analysis.

Core Facility for Biosafety is located in 1st floor of Institute of Biomedicine and Transaltional medicine, Ravila 14B.

The core facility of simulation technologies operates at the materials in extreme environmental conditions working group, and its main goal is to find a commercial application for computer simulation methods used and developed at the institute of technology. Examples of applied methodology are finite element analysis, fluid dynamics, molecular dynamics, density functional theory (DFT). We also use combinations of methods in a multiscale framework. The most important software used are Comsol Multiphysics, OpenFOAM, LAMMPS, Gaussian, VASP, FEMOCS.

The main focus of the core laboratory of simulation technologies is the provision of finite element method and fluid dynamics simulations to Estonian companies, as well as to the international market. In the international competitive situation, molecular dynamics and DFT are added. The core laboratory focuses primarily on solving nonlinear and multiphysics problems in situations that require adaptation of methodologies and are generally not cost-effectively available to companies when implementing standard software (Ansys, Solidworks Simulation, etc.). In this way, we acquire a market niche and ensure the effective use of highly qualified laboratory.

The experience so far in providing services to Estonian companies has demonstrated considerable interest on the part of companies in providing the corresponding services. In the expansion of the service offering, the biggest bottleneck has been the lack of information necessary for companies - they have not had the opportunity to find the provision of the corresponding service in TÜTI. The establishment of a core laboratory allows eliminating this bottleneck and making our competence and the solutions offered available to companies.
