PSF general information and operating guidelines
The aim of PSF is to provide protein production, 3D structure determination and biophysical characterization services to all researchers. We offer onsite access to instrumentation for high throughput crystallography and biophysical characterization and act as stepping-stone environment to large-scale infrastructures for X-ray data collection such as MAXIV and DIAMOND and MX software in a high performance computing environment via Swedish National Infrastructure of Computing (SNIC).
How to become a user
After an initial contact we arrange a meeting to discuss the details and timing of a project. For the national services an application form is then to be filled in. We try to accommodate requests as soon as possible and generally we can start to work on a project within a few days after agreement.
User fees and billing
The user fees for Swedish academics are based on cost for consumables, instruments, university OH, and part of the cost for staff and rent. Commercial users pay full costs including staff, premises and an added margin. Examples of Swedish academic user fees are listed below, for other services please contact us:

All experimental work is included in the invoices for protein production services. Projects/samples that fail during technically successful experiments are transferred back to the user together with generated data. Additional investigation or problem solving is performed after discussion and agreement with the user.
Instrument access is granted on fulfilling the user training and charged by user recording actual instrument use in log-books. Recurring failures to do so will result in a penalty fee and instrument access being revoked.
Invoice specifications are emailed to the user/PI quarterly and followed by an invoice sent by KI’s central economy service.
How to acknowledge PSF
To support PSF in future evaluations and applications all users are required to acknowledge experimentation or services performed at PSF in manuscripts submitted for publication.
