Instruct-HiLIFE Applications

Structural cell biology offers a wide range of different techniques for purification and analysis of biological complexes and their structures.
Biocomplex purification

Biocomplex provides purification technologies and expertise specializing in the ultracentrifugation techniques, monolithic chromatography and asymmetrical flow field-flow fractionation (AF4). Provided techniques can be used in different combinations to yield high quality samples in quantity.

  • Separation and purification of cells, organelles, macromolecules, macromolecular complexes, vesicles and viruses etc.
  • Ultracentrifugation combined with swing-out and fixed-angle rotors of different capacities;
  • Monolithic ion exchange chromatography;
  • Asymmetrical flow field-flow fractionation (AF4);
  • User training, assisted use of instruments, open access for trained users, specialist support and maintenance;
  • Project planning;
  • Full service packages on sample purification (including analysis of the quality and quantity);
  • Collaborative projects
  • Sample preparation for crystallisation
  • Pre-crystallisation tests
  • Screens for protein stability
  • Temperature dependence of three-dimensional crystal formation of protein
  • Protein crystallisation, membrane proteins especially
  • Screens for crystallisation conditions: random, grid and targeted screens
  • Protein optimisation using fluorescence-based thermal shift assay
