Topical Meeting on Large Proteins/MethylNMR

General information

SwedNMR, Gothenburg University and Dr. Björn Burmann is hosting a Topical Meeting on Large Proteins/MethylNMR March 13th and 14th, 2023 at the Swedish NMR Centre Gothenburg. The scope of the meeting is to better understand both the practical and theoretical aspects of exploitation of the the favourable properties of side-chain methyl groups in proteins and beyond extending the size limit of solution NMR applications. The target group is SwedNMR staff scientists and experts as well as other NMR spectroscopists interested to learn more about this topic.

If you are interested to attend please contact Alexandra Ahlner or Björn Burmann (, )
