Congratulations to Jens, Alvaro and our collaborator Michael in Tübingen! Our joint paper on flavin contents in mammalian cells just came out!

Flavins are not only co-factors of many essential redox reactions but also of our optogenetic receptors. ‘JensAro’ measured cellular flavin contents in our most recent paper using a sensitive capillary electrophoresis technique that was established with Michael Lämmerhofer from the University of Tübingen.

The next step of our work will be to find out how cellular flavin household ‘responds’ to overexpression of flavin binding proteins, e.g. a LOV domain, and how flavins are distributed on sub-cellular scales.
