What the tool is doing

These fluorophores/proteins are the label class whose photochemical reactivity under different light intensities provides the kinetic fingerprints used for discrimination.

Source 1DOI PubMed

RSFPs are fluorescent proteins that can be switched between optical states repeatedly with light. The review specifically centers on this subclass and its mechanisms and applications.

Source 2DOI PubMed

Resources required

Use requires optical illumination conditions that probe their reversible photoswitching behavior.

Source 1DOI PubMed

What problem it solves

In this paper they serve as labels that can be separated by kinetic behavior even when they are spectrally similar.

Source 1DOI PubMed

They provide genetically encoded optical contrast that can be repeatedly modulated for advanced imaging and control use cases.

Evidence Snippets

The abstract states that extra kinetic dimensions are introduced through illuminations of reversibly photoswitchable fluorophores at different light intensities, and that up to 20 among 22 spectrally similar reversibly photoswitchable fluorescent proteins were discriminated.

Each reversibly photoswitchable fluorophore can be characterized by a chromatic aberration-free kinetic fingerprint of photochemical reactivity that is recoverable with limited hardware, excellent photon budget, and minimal data processing.
