Photosensitizer KillerRed

- Genetically-encoded photosensitizer, direct expression in cells
- No exogenous chemical compounds or cofactors required
- No cell toxicity before light activation
- Induction by green light irradiation
- Successful performance in fusions
- Recommended for selective in vivo cell killing and CALI applications
