Evaluating Cellular Drug Uptake with Fluorescent Sensor Proteins

Rudolf Hovius, Kai Johnsson, Kui Thong Tan, Rudolf Griss, 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, Matthias Albert Brun, Kui Thong Tan, Rudolf Griss

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 ...

Semisynthesis of fluorescent metabolite sensors on cell surfaces

Horst Vogel, Kai Johnsson, Joachim Piguet, Luc Reymond, Matthias Albert Brun, Kui Thong Tan, Ruud Peters, Rudolf Griss

Progress in understanding signal transduction and metabolic pathways is hampered by a shortage of suitable sensors for tracking metabolites, second messengers, and neurotransmitters in living cells. Here we introduce a class of rationally designed semisynt ...

Semisynthetic fluorescent sensor proteins based on self-labeling protein tags

Kai Johnsson, Matthias Albert Brun, Marlon Hinner, Kui Thong Tan

Genetically encoded fluorescent sensor proteins offer the possibility to probe the concentration of key metabolites in living cells. The approaches currently used to generate Such fluorescent sensor proteins lack. generality, as they require a protein that ...
