They came up with a process in which researchers engineer a tetracysteine sequence (Cys Cys Xaa Xaa Cys Cys) into a protein and expose cells to a small, biarsenical derivative of fluorescein called ...

In this webinar, you will hear how label-free, ligand-binding-based assays can be used throughout the development and manufacturing of drug products for active concentration measurements, target ...

still fluorescing even when the actual protein is no longer present. In the study, the team employed both kinds of labeling simultaneously in samples. Visualizing the labels that way, they saw ...
