We are all very excited to have you all on board and we are looking forward to working with you and getting to know you!

DHL run 2017

The group participated in this year’s DHL 5x5k relay run, and got the fastest team in the department. Great job everyone!

It was a great afternoon and evening the running, socializing, food, and drinks! We have participated every year and we are of course back next year as well.

Two new publications about development of malaria vaccines

The group recently co-authored two publications in collaboration with Statens Serum Institut, Radbound University, and Bioneer regarding development of novel malaria vaccine candidates. The chimeric fusion proteins combine epitopes of key malaria parasite antigens including the highly disulphide-bonded Pfs48/45 antigen, and are potential candidates for a multi-stage malaria vaccine that targets both the mosquito and human life-cycle stages of the parasite.

Work has been done optimizing expression, refolding, purification as well as analysis and characterization of the protein antigens. A detailed mapping of the cysteine connectivity of the Pfs48/45 antigen was performed by mass spectrometry as well.

ASMS Annual Conference on Mass Spectrometry and Allied Topics

ASMS is the biggest conference about mass spectrometry in the world with 384 scientific talks and over 2700 poster presentations. Kasper, Jens, Ulrik, Esben, and Anne Kathrine went to Indianapolis the 2.-8. June 2017. Jens, Ulrik and Esben presented posters about their work and Anne Kathrine gave a talk about her research in the “Membrane Proteins” session.

ASMS was a great opportunity to hear about the newest and most exciting research in mass spectrometry as well as great networking possibilities. There was also time for exploring the city and trying the local food and drinks. The group is already looking forward to ASMS 2018, this time in San Diego!

Patrick defended his PhD

Today the first PhD student graduated from the group, after successfully defending the PhD. The title of the project was “Probing the Structural Dynamics of Membrane Proteins by Hydrogen/Deuterium Exchange Mass Spectrometry”.

The assessment committee consisted of: Prof. Poul Nissen from Aarhus University, an expert in membrane protein. Prof David Schriemer from University of Calgary, an expert in mass spectrometry based techniques including HDX-MS. And chairman Marco van de Weert from the department, who is an expert in various techniques for assessing protein structure and stability.

On the picture Patrick is flanked by his supervisors Kasper and Claus Løland and the PhD assessment committee on the left, Marco van de Weert, Poul Nissen and David Schriemer.

It has been a great pleasure having Patrick in the group, but we will keep in touch!

International Conference on Hydrogen Deuterium Exchange Mass Spectrometry

The 1st International Conference on Hydrogen Deuterium Exchange Mass Spectrometry (IC HDX) took place in Gothenburg, Sweden. 150 people with a strong interest in HDX-MS from both industry and academia joined for the workshop and the conference. Kasper was co-organizing the conference, but also Ellie, Esben, Gerard, Rasmus and Ulrik from the group participated. And Kasper, Esben and Ulrik gave a presentation at the conference.

It was great to see to many peers and experts in the field of HDX-MS to come together and exchange ideas and share experience. We are already looking forward to the next IC HDX conference in 2019, this time in Canada!

Kasper presented at ESAC

Eleanor, Jens, Ulrik and Kasper went to the annual Executive Seminar in Analytical Chemistry (ESAC), which took place in Copenhagen at the Scandic Hotel on the 26 April. It was a great way to keep updated on emerging topics and to network with analytical scientists in Denmark.

Kasper did a presentation titled “Studying the conformation and dynamics of membrane proteins through hydrogen/deuterium exchange and mass spectrometry” in the Life Scieence/Biotech session.

New publication from the group

Rasmus, Nanna, Tam, Henrik and Kasper have recently published a paper in the scientific journal Analytical Chemistry, titled: “Thiol-ene Monolithic Pepsin Microreactor with a 3D-Printed Interface for Efficient UPLC-MS Peptide Mapping Analyses”.

The work was done in collaboration with the Microscale Analytical Systems Group.

 

Ulrik awarded with EliteForsk travel grant

Ulrik was awarded with the EliteForsk-rejsestipendium (Elite research travel grant). The 200.000 DKK grant is awarded to enable very talented PhD students to carry out longer research stays at the best research environments world-wide. Ulrik will use to visits labs in Oxford and Manchester and to join international conferences. The grant was awarded by Crown Princess Mary and minister Søren Pind on behalf of the Ministry of Higher Education and Science.

Congratulations to Ulrik!

New publication in JASMS

Zeinab and Kasper have together with collaborators from Biogen, published an article in Journal of The American Society for Mass Spectrometry.

A customized HDX-MS method was developed to inform on the structure of therapeutic proteins at very high concentrations (>100 mg/ml). This method enables analysis of the higher-order structure of the protein in the high-concentration formulation without prior dilution, and will potentially optimize development of highly concentrated formulations of protein drugs at low volumes. High concentration formulation of proteins could possible enable advantageous subcutaneous injections.

The article can be found here: Conformational Analysis of Proteins in Highly Concentrated Solutions by Dialysis-Coupled Hydrogen/Deuterium Exchange Mass Spectrometry

New paper from the group

Kasper and Pernille have published a paper in MCP “A two-pronged binding mechanism of IgG to the neonatal Fc receptor controls complex stability and IgG serum half-life“.

Using HDX-MS and affinity chromatography they have studied the binding interactions of the neonatal Fc receptor (FcRn) and the IgG briakinumab. Correlate the occurrence of excessive FcRn binding to an unusually strong Fab-FcRn interaction and therefore the unusually short half-life of briakinumab.

Group receives ITN European Industrial Doctorates Grant

The group and project partners 1.1 million € for starting VADEMA (Doctoral Industrial School for Vaccine Design through Structural Mass Spectrometry). The grant enables hiring four PhD students, which will spend 18 months in our group and 18 months at GSK Vaccines in Italy.
We are looking forward to welcoming the new PhD students in the group when they start.
