X-ray Data Collection

Expose is based at the Swiss Light Source (SLS) were it provides fast and reliable services in X-ray protein crystallography for pharmaceutical and biotechnological companies.

Our services are charged by the hour.


Data collection at the protein crystallography beamlines

The concept of our data collection service:

  • Customers purchase the beamline shifts independently from the SLS Technology Transfer AG. If required, Expose assists in shift purchase
  • Expose allocates the shifts in accordance with the customers timeline needs, the beamline schedule and the schedule of the Expose team
  • The Expose team carries out the screening and data collection according to the wishes of the customers and provides fast data transfer

Expose – Günter FritzIt is our objective to interfere as little as possible with the customers existing processes and standards.

For instance we process crystals stored in all available pucks and canes without restriction.

Also, we require no separate standard sample sheet, but work with the existing system of our customers.




Expose – Joachim DiezFor interested companies which have only few crystals and do not wish to purchase entire shifts, the SLS offers a Mail-in-Crystallography Service which is operated by Expose as well.


Data Processing

We routinely process the data crudely on-the-fly for quality control purposes.

If wished, we also process the data according to your predefined criteria. Just provide us your desired R-meas and I/I(sigma) cut-offs and we will provide you with mtz-files of the datasets.
