Here is – for the moment, before it’s published on the Jacobs website – our press release for the Tetramer Shop:
Jacobs University Bremen launches a company for biomedical reagents
T cells are white blood cells of the immune system that have amazing properties: they can detect cancer cells and virus-infected cells in the body, and they can often even attack and eliminate such disease agents. This is why T cells are an important part of the immune response that a patient makes against tumors and viruses. Researchers from Jacobs University Bremen, led by Prof. Sebastian Springer, have now co-founded a company to sell reagents that help doctors and scientists track down T cells and determine what disease factors they can attack.
When an immune response against a tumor takes place, the tumor-fighting T cells in the blood of the patient multiply. To find out how well a treatment is working, scientists and doctors want to check how many tumor-specific T cells there are. The tumor-specific T cells can be detected because they carry on their surface a so-called T cell receptor. The scientists use a so-called MHC protein, which binds to the T cell receptor, to color these T cells and observe them under the microscope or in a high-throughput machine called a flow cytometer.
The MHC proteins that are needed for T cell detection were previously really difficult to produce, and that used to be a bottleneck in research and diagnosis. “Whenever a researcher needed MHC proteins, they had to ask a company to make them, and the process took four to six weeks”, explains Springer. “Of course, that created big problems if they had a sick patient they wanted to diagnose, or if they were following a really urgent scientific project. The problem was that every MHC protein contains a little piece of a tumor or virus called a peptide, which varies from one patient to the other, and without the peptide, the entire protein complex was unstable and perished quickly, even if it was kept in the freezer.”
Already some years ago, Springer and his group constructed a super-stable form of the MHC protein by introducing a so-called disulfide bond. As a result, the MHC proteins are now stable without the little peptide and can be stored in their empty form. Just before use, the patient-specific peptide is then added. When Springer and his group saw the promise of this new technology, they filed a patent application.
“Our colleagues at the Technical University of Denmark in Copenhagen then showed that the disulfide-stabilized MHC protein can be used in diagnostic procedures on patients”, says Springer. “Together, we then realized that we should set up a company to sell our new MHC proteins.” The new company, called Tetramer Shop (after the scientific name of the MHC protein reagents), opened on March 1st. Their customers are research and diagnostic laboratories worldwide, and the first orders have already been filled. The company is owned by the scientists who developed and validated the technology, and by Jacobs University.
“It’s a beautiful example of what is possible at Jacobs”, says Ronald Kieschnick, Head of Research and Transfer at Jacobs University, who helped to get the company under way. “Here, research results are being transferred directly into application. We’re very happy that Tetramer Shop is now able to bring their products to the user.”

Gosia meeting Randy Schekman:
February 26, 2019:
Our new paper just got published:
Ida Hafstrand, Ece Canan Sayitoglu, Anca Apavaloaei, Benjamin John Josey, Renhua Sun, Xiao Han, Sara Pellegrino, Didem Ozkazanc, Renée Potens, Linda Janssen, Johan Nilvebrant, Per-Åke Nygren, Tatyana Sandalova, Sebastian Springer, Anna-Maria Georgoudaki, Adil Doganay Duru, and Adnane Achour:
Successive crystal structure snapshots suggest the basis for MHC class I peptide loading and editing by tapasin.
PNAS, February 26, 2019;
The paper has a long history, way back to at least 2014 when Anca Apavaloaei did her summer internship in Adnane’s lab at Karolinska. She managed to crystallize H-2Kb with the GL dipeptide. Hers is Figure 1 and the first crystal structure of class I with a dipeptide! Congratulations Anca!
February 21, 2019:
The website of the Tetramer Shop went online! They are not yet taking orders (another few days) but you can look at it already.
February 9, 2019:
Yesterday, the new company based on the disulfide technology was incorporated in Copenhagen. It’s owned by our alumnus Sunil, by his current boss Sine Hadrup, by her employee Søren Jakobsen, by myself, and by Jacobs University. It’s called “Tetramer Shop“. Watch this space 🙂

Happy New Year to all. There is a great new review on class I endocytosis by our lab alumnus Sebastián Montealegre: “Endocytic Recycling of MHC Class I Molecules in Non-professional Antigen Presenting and Dendritic Cells” (Front. Immunol., 07 January 2019; https://doi.org/10.3389/fimmu.2018.03098).
December 1, 2018:
Cindy and Sebastian organized, together with Gerhard Schütz and Eva Sevcsik of the Technical University of Vienna, the 682. WE-Heraeus-Seminar on MICRO- & NANOSTRUCTURED BIOINTERFACES. It was held at the Physikzentrum in Bad Honnef, close to Bonn.
This turned out to be an excellent meeting with a lot of young people and very good discussions in the emerging field of structured biointerfaces. We hope that this will be the first in a series!

Our lab member Chantal Bohn wrote a beautiful text for Humboldt Day today:
A modern scientist from the past
The 14th September 1769 was for most people an ordinary Thursday. What they don’t know is that on this day the German scientist Friedrich Wilhelm Heinrich Alexander von Humboldt was born in a small castle near Berlin. His life was an outstanding journey through the miracles of our planet. A journey that brought him from the mines in Germany deep underground to the Chimborazo volcano in Ecuador several kilometers above sea level. A journey that let him discover the tiniest details and allowed him to connect them to the bigger picture. And most importantly, he knew that life doesn’t lose it’s magic when you dig into its most hidden secrets (like the function of MHC Class I proteins) – it just gets more fascinating (like MHC Class I proteins). Alexander von Humboldt combined profound theoretical knowledge with practical experience which he first discussed with experts in Paris, London and the United States and later shared with the public all over the world. Not all of this methods are up-to-date, but we can still learn a lot from him, especially one thing: the fascination for the overwhelming beauty of nature.
September 6, 2018:
Cindy’s new paper on micropatterns has been published in eLife!

I am deeply impressed by the feature article “Losing Earth: The Decade We Almost Stopped Climate Change” in the New York Times Magazine. If the climate catastrophe is almost inevitable, then our first and foremost duty – besides activism – is to train the next generation of students in thinking scientifically so they do not fall victim to the manipulation tactics of industry and the selfishness of politicians.
- I came across this through the article “Die Katastrophe hätte verhindert werden können” (German) in SPIEGEL.
- Here is another perspective on climate change: “The Uninhabitable Earth” from the New York Magazine.
- And here is another slightly more positive view from the Guardian: “Don’t despair – climate change catastrophe can still be averted“.
- The impressive article “Bald gibt es kein Zurück mehr” (German) in Die Zeit.

The June issue of ‘Biospektrum’ has our review article “Antikörper-Mikropatterns zur Analyse von Proteininteraktionen in Zellen” (in German). The English abstract is:
“The study of protein-protein and protein-ligand interactions at the cell surface is especially important for understanding many processes that are central to the life of the cell. Here, we present a novel two-hybrid assay based on antibody micropatterns that allows the visualization, measurement, and quantification of such interactions in the natural environment of the cell. We demonstrate the potential of our micropatterns with an immunological example.”
Also: Today on the Jacobs webpage is an article about Venkat’s Cell Reports paper!

I was sad to hear that Hellmuth Möhwald passed away. He was the pioneer of polyelectrolyte microcapsules (and a lot of other things). We learnt from him through his former student, Tatiana Kolesnikova. I remember presenting our microcapsule plans to him at the Max Planck Institute in Golm, in 2011.
Happy Pi Day everyone! The best Pi Day activities are at the Exploratorium in San Francisco: https://www.exploratorium.edu/pi/ They invented Pi Day, after all.
And: congratulations to our lab member Evi Zhuleku on admission to the Göttingen Molecular Biology graduate program!
February 20, 2018
I was sad to hear that Günter Blobel has passed away. He was one of the true giants of molecular cell biology, the discoverer of topogenic sequences in proteins. I applied to him for a postdoc position in 1996 and I remember spending a whole Sunday afternoon in his office at Rockefeller, and presenting my job talk to him alone. We ate from a big basket of oranges that he had brought from the market. I ended up not taking his offer but went away deeply impressed by the personality.
January 29, 2018
Our friend Jon Yewdell at NIH has written a great book about science: “Truth Wins”. It is an account of his own scientific career, with (in a second chapter) a lot of advice to people considering a scientific career. He has made it available for free, it is really worth reading.

How can science be published more fairly?
This topic is important to our recent guest, Randy Schekman. Inspired by him, I am putting together a small collection of links here:
- An article by the Guardian (June 27, 2017) that describes what is wrong in scientific publishing: “Is the staggeringly profitable business of scientific publishing bad for science?“
- Randy’s recent interview in SPIEGEL ONLINE: “Aufgebauscht, bis es falsch wird” (in German, Google translated)
- The panel discussion at Jacobs University on June 8, 2017, with Randy Schekman, Bernd Pulverer (of the EMBO Journal), and Gerard Meijer (of the Max Planck Society): “Mind the Gap – why our society needs to share knowledge“
- An older article in the Guardian (December 9, 2013) about Randy’s original refusal to publish in Cell, Nature, Science, and similar journals:”Nobel winner declares boycott of top science journals“.
June 30, 2016

November 3, 2016
We remember Stefan Jentsch who passed away last week. Stefan was a director at the Max Planck Institute for Biochemistry in Tübingen. After his postdoc with Alexander Varshavsky, he isolated the first ubiquitin conjugating enzymes from yeast and made very important contributions to the understanding of the big role that the ubiquitin system plays in protein degradation and in the supervision of the integrity of the genome. Stefan was the supervisor of Sebastian’s diplom (MSc) thesis at the Max Planck Institute in Tübingen.
As a student, I loved Stefan’s anarchic and irreverent spirit, in science and life. In Tübingen, someone had hung up a poster in the hallway, showing a beautiful mountain lake in Switzerland. One day, I watched Stefan cut out from Post-It notes the parts of a giant sea snake monster and attach it to a corner of the lake, so people would see it at the second glimpse. At the time, it was shocking to me that a Professor would do such things. Stefan – you continue to inspire me to this day :-). Thank you.
October 12, 2016
I would like to congratulate our lab alumna Patrycja Kozik (BCCB class of 2004) on taking up her position as a Research Group Leader at the MRC Laboratory of Molecular Biology in Cambridge. She will work on antigen presentation through MHC class I in dendritic cells.
