Yellow fluorescent protein TurboYFP

- Super bright true-yellow fluorescence
- Emission wavelength is ideally positioned between those of green and red fluorescent proteins
- Fast maturation, high pH-stability and photostability
- Destabilized variant is available
- Recommended for gene expression analysis and cell labeling
