Access to the HTX lab for External Users



BioStruct-X is a project funded by the Seventh Framework Programme (FP7) of the European Commission that establishes a state‐of‐the‐art coordinated and multi‐site infrastructure to support access for established and emerging key methods in structural biology. Eleven facilities from across Europe provide 44 installations for applications in small angle X‐ray scattering (SAXS), macromolecular X‐ray crystallography (MX) biological X ray imaging (XI) protein production and high throughput crystallisation (PP & HTX).

The aim of BioStruct-X is to provide a consolidated platform that brings together all relevant methods in structural biology – creating a single gateway to Europe’s leading European synchrotron facilities and associated infrastructures, ultimately to the benefit of the overall user community.

BioStruct-X cooperates with the ESRFI project Instruct (Integrated Structural Biology Infrastructure for Europe) in aiming to provide an integrated and coordinated technology platform to all relevant methods in structural biology.

Next application deadline: 15 September 2015


To apply for access please fill the form on biostruct logo web site

In order to use our service, select SP (single proposal) while filling the application form. The applicant has to choose the number of HTX units to be granted. One HTX unit corresponds to one 96-well crystallization plate (one to three samples can be set up per plates). Therefore, we recommend to request for 50 HTX units.


Mode of Operation

At the HTX lab, the user designs the experiments through our dedicated web interface. Details on the methods and possible experimental parameters are available through our web portal, however specific and advice can be requested from the HTX lab staff at This email address is being protected from spambots. You need JavaScript enabled to view it.. Every individual crystallization experiment is submitted to a quality control process. After the crystallization experiments are set up the user receives an experimental report including data on quality control. Results are available in real-time through our web-based Crystallization Information Management System (CRIMS), which is synchronized with the ESRF sample changer and data collection system ISPyB (this requires the use of SPINE sample loops with 2D-data matrix). Plates are made available to users upon requests, (typically during their next visit to the ESRF beam lines). If necessary, lenses and liquid nitrogen will be made available for crystal mounting and freezing (but no sample loops).

Currently, we are also offering remote access to automated crystal harvesting and cryo-cooling (in collaboration with the Instrumentation Team, EMBL Grenoble) as well as in situ x-ray diffraction experiments (in collaboration with BM14, ESRF), through our own CrystalDirect technology : Acta Cryst. (2012). D68, 1393-1399.



The laboratory staff is available for any specific request and can advice users on the best choices for their projects. In addition to the standard procedures, a number of alternative protocols are available to support samples with specific requirements (low stability, detergents etc,). Support for the design of optimization experiments is also available. You can contact the laboratory staff at This email address is being protected from spambots.
