Services

Page is currently under reconstruction.

List of services provided by CF BIC. 

Measurements are performed by CF BIC staff after obtaining samples from users. The speed of service depends on chosen technique and current workload of CF staff, however, the results are typically available within a week.

 Since 2021, the services are requested via booking system.



Biomolecular characterization and interaction:

Analytical SEC-MALS

Analytical size-exclusion chromatography coupled to an array of detectors including UV-VIS spectrometer, refractometer, viscometer and static light scattering (RALS/LALS). Suitable for analysis of sample purity, oligomeric state of proteins, study of complexes and other experiments.

For more details, contact CF responsible person Josef Houser.

Sedimentation velocity

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

Sedimentation equilibrium method can be used for accurate determination of molecular weights of various biomolecules and the study of their interactions.

Differential scanning calorimetry

PEAQ-DSC is differential scanning microcalorimeter with <200 µl volume of sample capillaries. DSC technique measures the heat changes that occur in the (bio)molecule sample solution during a controlled increase or decrease in temperature, on the basis of a temperature difference between the sample and the reference material. Automated version of PEAQ-DSC enables to run up to 282 samples in a row unattended.

Initial training for instruments in user mode:

Initial training for instruments which are operated by users him/herself. This includes Octet RED96e (BLI), Jasco J-815 (CD), SpectroLight 600 and DelsaMax Core (DLS),  Biacore T200 (SPR), multichannel SPR imaging system, Auto-PEAQ DSC and VP-DSC, Prometheus (DSF), VP-ITC, Monolith NT.115 Nano and Monolith NT.115 Pico (MST),  Biacore T200 (SPR), multichannel SPR imaging system, microdeposition system for biosensor arrays, gradient incubator for optimizing protein crystallization temperature (TG-40) and Biospectrometer kinetic (UV-VIS KINETIC)

Training is performed by CF BIC staff - responsible person for each instrument. Without this training users cannot operate the instruments on their own.
