Cyan-to-green photoswitchable fluorescent protein PS-CFP2
- Irreversible photoconversion from a cyan to a green fluorescent form
- High contrast of photoconversion
- High pH stability allowing labeling of acidic organelles
- Recommended for tracking cell, organelle, and protein movement, and for determination of protein half-life
 | PS-CFP2 is an improved mutant of the photoswitchable monomeric fluorescent protein PS-CFP [Chudakov et al., 2004]. PS-CFP2 exhibits faster maturation and a brighter fluorescence both before and after photoswitching than that of PS-CFP.
PS-CFP2 is capable of irreversible photoconversion from cyan to green fluorescent form in response to 405 nm light irradiation. It is recommended for real-time in vivo tracking movement of cells, organelles, and individual proteins [Chudakov et al., 2007]. It can also be applied for determination of protein half-life [Zhang et al., 2007]. In addition, PS-CFP2 can be used as a routine cyan fluorescent tag (excitation maximum at 400 nm and emission maximum at 468 nm) at moderate excitation intensities and as a donor in FRET applications [Souslova and Chudakov, 2006]. |
