Partnership between LP3 and DEMAX
In 2016, the DEuteration and MAcromolecular Xtallization (DEMAX) platform of the European Spallation Source ERIC (ESS) moved into Biology House A at Lund University and co-localized with the LP3. DEMAX and LP3 are collaborating to coordinate their efforts to develop cost-effective production of deuterated biomaterials (lipids and proteins) for neutron-based methods such as protein crystallography, neutron reflectometry, and small angle neutron scattering. Perdeuterated proteins will also be crystallized and optimized to promote maximal crystal volumes as required by neutron protein crystallography.
Access to both state-of-the-art large scale facilities (MAX IV for X-rays and ESS for neutrons) will increase the local and international capacity for innovation in the life sciences. Partnering between LP3 and DEMAX enables effective coordination of capabilities in the region. To enable efficient use of these unique and powerful facilities by Lund researchers, Lund University hosts the protein production platform, LP3. LP3 offer services to users from construct design all the way to crystals, if required. The LP3 specializes in protein production, protein purification, biophysical characterization, isotope labelling of both proteins and lipids, and crystallization. DEMAX is an ESS platform dedicated to international users of the neutron scattering facility and will support deuteration of biomolecules and small molecule chemicals, as well as large crystal growth for neutron protein crystallography. The synergies between LP3 and DEMAX are very strong and we look forward to a productive collaboration.
Maria Gourdon, new LP3 scientist responsible for crystallization
Maria Gourdon, PhD, has taken over the responsibility for the crystallization part of LP3. Maria has a background in membrane protein structural biology, handling projects from gene to crystals, structural determination and refinement. Contact her at maria.gourdon [at] biol.lu.se.
New system for microbiological growth monitoring
A Bioscreen C system for microbiological growth studies is now available at LP3. The Bioscreen C can incubate, shake, and measure the turbidity (OD) of up to 200 samples simultaneously.
LP3 and the crystallization facility is "Infrastructure of the month - May"
Protein Production Network Sweden (PPNS) pilot expression screen completed
LP3 is part of the Protein Production Network Sweden (PPNS) that aim to make multiple protein expression hosts, methodologies and competence in protein production available to the Swedish academic life science community. Collaboration between Swedish protein production sites is crucial in order to solve complex scientific questions and in a pilot effort to test a new joint approach, five proteins of varying origin were selected for multi-host expression screening performed the different sites. The screen was competed in November 2014 and a report (pdf; kB)of the pilot study was made.
A network of Swedish protein production facilities
LP3 is taking part in the formation of a network of Swedish protein production facilities together with the Protein Science Facility at Karolinska Institutet/SciLifeLab, Mammalian Protein Expression at Göteborg University, Protein Expertise Platform at Umeå University and the Drug Discovery and Development platform at SciLifeLab. The network will coordinate optimized use of resources and facilitate increased knowledge transfer.
Eukaryotic expression system
Right now LP3 is in the process of establishing the Baculovirus Expression Vector System (BEVS) – a system for expression of recombinant proteins in insect cells. This system will complement the current LP3 capabilities to express proteins in bacteria and yeast. The BEVS, being a eukaryotic expression system, has its strength in producing proteins from higher eukaryotic organisms that have failed to be produced in E. coli and a strong track record for production of membrane proteins, large proteins and multi-subunit complexes, for structural as well as functional studies.
