Resources

Methods and Techniques used in A01 and A05 at the Charité: Structure biology methods:
  • Protein X-ray crystallography, membrane protein crystallization, lipidic cubic phase (LCP) crystallization (e.g. TTP Labtech’s mosquito, Gryphon-LCP crystallization and PRIMA Xtallob robots; Formulatrix – Rock Imager 182/54; High-end Stereo microscope Leica M205; Formulatrix – MUVIS)
  • X-ray data acquisition: synchrotrons (e.g. BESSY and DESY (Germany), ESRF (France), or in house rotating anode generator (MicroMax007 Microfocus)
  • Free-electron laser (XFEL) X-ray data acquisition: (e.g. LCLS-SLAC (USA) or SACLA-Spring-8 (Japan))
  • Cryo-electron microscopy (in house) – high-end 300 kV FEI Titan Krios G3 cyro-TEM System/ K3 direct electron detector/ Volta phase plate/ energy filter, Vitrobot, 120kV TEM for sample screening
GPCR production methods and signaling/ligand-binding assays:
