Insufficient quality control and characterisation of a produced protein batch might lead to unreproducible results and misleading conclusions.

All PPNS-laboratories support the guidelines issued by The Association of Resources for Biophysical Research in Europe ( ARBRE-MOBIEU) and Protein Production and Purification Partnership in Europe (P4EU) regarding quality control of recombinant proteins.

Quality measures from the process and documentation sufficient to repeat the experiment always accompany the final product.


The Protein Production Network Sweden (PPNS) is an informal network formed in 2013 between protein production facilities at Swedish universities. The overall aim is to make competence and protein production methodologies available to the Swedish academic life science community and to make best use of our available resources.

PPNS facilities participate on different terms depending on their local structure and governance. Within the network we can transfer projects between the sites and help scientists to find the facility best suited for a specific project. Please contact any of the facilities, contact information can be found at each site’s web page.

PPNS has also useful contacts with other protein production sites that are not devoted to service but still might be able to assist or collaborate in projects within their specific area of expertise. Therefore, feel free to contact us even if you do not find the particular service you look for on our web pages.
