TurboFPs

- Superbright fluorescence
- Very fast maturation
- For research and commercial use

TurboFPs are fluorescent proteins of different colors characterized by superbright fluorescence and superior fast maturation. These proteins are recommended for applications requiring fast appearance of bright fluorescence, including cell and organelle labeling or tracking promoter activity.

* Brightness is a product of extinction coefficient and quantum yield, divided by 1000.
** For stable cell lines generation and organelle labeling we recommend that you use PhiYFP.
