Bioluminescent sensor proteins for point-of-care therapeutic drug monitoring

To ensure efficacy but avoid toxicity, many drugs require monitoring of their concentrations in the patient’s blood during therapy. Currently, therapeutic drug monitoring (TDM) is done in diagnostic laboratories that need trained personnel and expensive in ...

Semisynthetic sensor proteins enable metabolic assays at the point of care

Kai Johnsson, Rudolf Griss, Qiuliyang Yu, Lin Xue, Julien Hiblot

Monitoring metabolites at the point of care could improve the diagnosis and management of numerous diseases. Yet for most metabolites, such assays are not available. We introduce semisynthetic, light-emitting sensor proteins for use in paper-based metaboli ...

Evaluating Cellular Drug Uptake with Fluorescent Sensor Proteins

Kai Johnsson, Rudolf Hovius, Rudolf Griss, Kui Thong Tan, Silvia Scarabelli

We are introducing a new approach to evaluate cellular uptake of drugs and drug candidates into living cells. The approach is based on converting the protein target of a given class of compounds into a fluorescent biosensor. By measuring the binding of dif ...

A Semisynthetic Fluorescent Sensor Protein for Glutamate

Kai Johnsson, Luc Reymond, Rudolf Griss, Matthias Albert Brun, Kui Thong Tan

We report the semisynthesis of a fluorescent glutamate sensor protein on cell surfaces. Sensor excitation at 547 nm yields a glutamate-dependent emission spectrum between 550 and 700 nm that can be exploited for ratiometric sensing. On cells, the sensor di ...

Luciferases with tunable emission wavelengths

Kai Johnsson, Luc Reymond, Rudolf Griss, Alberto Schena, Olivier Vincent Sallin, Qiuliyang Yu, Lin Xue, Julien Hiblot

We introduce luciferases whose emission maxima can be tuned to different wavelengths by chemical labeling. These tunable luciferases are generated by inserting the small luciferase NanoLuc into the structures of the self-labeling proteins SNAP-tag or HaloT ...
