RESEARCH

 

DEUTERATED RHODAMINES

We develop and use "d12" deuterium congeners of rhodamines that exhibit higher brightness and longer lifetimes with reduced bleaching versus their parent fluorophores TMR and SiR. Have a look at improved Förster resonance energy transfer (FRET), fluorescence activated cell sorting (FACS), fluorescence lifetime microscopy (FLIM) and stimulated emission depletion (STED) nanoscopy in our latest preprint.

MEMBERS

JOHANNES BROICHHAGEN

Group Leader

JB studied chemistry at the University of Erlangen-Nuremberg including a one-year stint with Marcus Weck at NYU and graduated in 2010 with honors. He then joined the group of Dirk Trauner at LMU Munich to dive into Chemical Biology and obtained his PhD in 2014. Next, he was working with Kai Johnsson at EPF Lausanne and at the MPI for Medical Research in Heidelberg. Since March 2020, he joined the FMP in Berlin as a Junior Group Leader.

RAMONA BIRKE

Technical Assistant

Ramona studied Biology with a focus on genetics and molecular biology at the Humboldt University Berlin, graduating 2010 in Molecular Ecology. After a stint at WITA GmbH, she joined the FMP as technical assistant in 2011, working in the field Molecular Cellular Physiology and Mass Spectrometry. Enjoying nature and being a passionate hiker in her free time, she teamed up with JB in 2020 to support and pursue our quests in Chemical Biology.

KILIAN ROSSMANN

PhD Student

Kilian studied chemistry at the Julius-Maximilian-University Würzburg (JMU) with focus on Organic, Physical and Medicinal Chemistry. For his Master Thesis he joined the group of Dirk Trauner at New York University (NYU), where he worked on photoswitchable PROTACs. After graduating in 2019, Kilian decided to join JB’s lab in 2020 to work on novel imaging techniques.
