Sample Preparation & Characterisation

  • Sample quality control for integrative projects
  • Sample preparation and optimisation
  • High-throughput crystallisation

PC

Available Instruments

  • VP ITC, MicroCal - Isothermal Titration Calorimetry, study of biomolecular interactions in solution
  • PEAQ-ITC, MicroCal - Isothermal Titration Calorimetry, study of biomolecular interactions in solution
  • Monolith NT.115 (Microscale thermophoresis), NanoTemper - measuring binding affinities (labelling of 1 partner required)
  • Monolith NT. Label-free (Microscale thermophoresis), NanoTemper - measuring binding affinities (label-free)
  • DLS Nanostar (Dynamic light scattering), Malvern - particle size measurements. Addressing dispersity/ aggregational state of samples.
  • Biacore T200, GE - SPR, interaction of biomolecules and kinetics
  • CD (Circular Dichroism), Applied Photophysics - Secondary structure analysis.
  • Prometheus NT.48 with backscattering optics (nano-Differential Scanning Fluorimetry technology), NanoTemper - study protein stability and protein aggregation.
  • FTIR (Fourier Transform Infrared Spectrometer) Bruker - Protein spectrum. Analysing protein signals from formulation components.
  • MALDI TOF, Bruker/CovalX - Determination of the molecular mass of protein samples and peptides resulting from proteolytic digestions. CovalX HM4 High-Mass System enables protein complex analysis and intact protein analysis.
  • Octet RED96 System, PAL ForteBio - 96-well characterization of protein-protein and protein-small molecule binding kinetics, determination of protein concentrations.
  • SPARK 20M Plate reader, TECAN - Detection Absorbance, Fluorescence intensity, FP, TRF, FRET, TR-FRET, luminescence (flash, glow, multi-colour), Alpha Technology, Automated live cell imaging
  • Stopped-Flow, Applied Photophysics - Time resolved experiments
  • Mass photometer, Refeyn - can monitor protein-protein interactions at a single-molecule level with high-sensitivity and can at the same time determine molecular weight of proteins and protein complexes with a high dynamic range and great accuracy. The mass photometer is an ideal tool for quality control in the protein structural analysis workflow as it can assess the molecular mass and the oligomerisation status of a sample in one measurement.
  • SSM-based electrophysiology, SURFE²R N1 - designed for the measurements of electrogenic transporters (symporters, exchangers and uniporters) and pumps. Usually these proteins have low turnover rates compared to ion channels. SURFE²R technology compensates for that with a large sensor size which allows for the measurement of up to 109 transporters at the same time to yield the best signal to noise ratio.

We facilitate access to Biological SAXS measurements with near-real time outputs of structural parameters and low-resolution solution-state structures in collaboration with the SAXS group.

Access & Team

Access

The PC facility is a fee-for-service (non-profit) technology platform operated by EMBL in Hamburg. No service fees are charged for usage of this equipment by EMBL, CSSB and beamline users. An online system (iLAB) to streamline the process of booking instruments, ordering and billing core service requests is in place and in routine use.

All users must follow a safety training before working in our laboratories. Complete the SPC safety briefing and examination before your visit though SMIS. Please go to the Safety tab and select "Standard Training"
