Services
List of services provided by CF BIC. Measurements are performed by CF BIC staff after obtaining samples from users. The results are available within a week.
Services are booked via intranet system (for more information HERE)
Sample quality assessment
Sample quality service enables to characterize protein sample prior to more advanced experiments. It includes measurement of intact mass (MS), aggregation content (DLS) and temperature stability (nanoDSF).
For more details, contact CF responsible person Josef Houser.

NEW
Sedimentation velocity method can be used for determination of sample dispersity, oligomeric state of proteins, the shape of the particle and it is also suitable for analysis of aggregates and a study of biomolecular interactions.
Sedimentation equilibrium method can be used for accurate determination of molecular weights of various biomolecules and the study of their interactions.

Advanced crystallization techniques
Optimization of protein crystal production in large scale (manual setting), Membrane protein crystallization techniques, Crystallization by dialysis or using capilaries. The service price is calculated individually. Contact the responsible person for details.
Initial training for instruments in user mode (operated by users him-herself)
Initial training for instruments which are operated by users him/herself. This includes Biacore T200 (SPR), multichannel SPR imaging system, DelsaMax Core (DLS), Jasco J-815 (CD), VP-ITC, VP-DSC, Monolith NT.115 Nano (MST), Prometheus (DSF), microdeposition system for biosensor arrays and gradient incubator for optimizing protein crystallization temperature.
Training is performed by CF BIC staff - responsible person for each instrument. Without this training users cannot operate the instruments on their own.
Service includes consulting with specialist, expert data evaluation, advanced experimental design or personal user support during measurement.
