Fluorogenic probes targeting G-quadruplex structures have emerged as the promising toolkit for functional research of G-quadruplex and biosensor development. However, their biosensing applications are ...

Self-labeling protein tags such as SNAP-tag offer the opportunity to attach bright and photostable synthetic fluorophores to proteins of interest for later analysis, and are widely used in ...

There are no methods sensitive enough to detect enzymes within cells, without the use of analyte labeling. Here we show that it is possible to detect protein ion signals of three different ...
