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.​​

Sedimentační rovnováha

Metoda sedimentační rovnováhy se používá pro přesné určení molekulární hmotnosti biomolekul a pro studium jejich interakcí.

Biological Small-angle X-ray scattering


SAXS is used for the determination of the integral structural parameters, shape reconstruction, determination of the oligomeric state in solution, unraveling of the quaternary structure of protein complexes, and modeling of molecular flexibility. CF BIC offers SAXS data acquisition and SAXS data analysis services.

Contact the CF responsible person Tomáš Klumpler for details.

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.
