Takara Photoactivatable mCherry fluorescent protein

Living Colors PAmCherry is a photoactivatable fluorescent protein (PAFP) derived from the red fluorescent protein mCherry. PAmCherry is non-fluorescent until it is exposed to 350- to 400-nm light. By selecting which cells or cellular regions to activate, you can track cells, organelles, or proteins of interest against a dark background using this photoactivatable fluorescent protein.

Living Colors PAmCherry is a photoactivatable fluorescent protein (PAFP) derived from the red fluorescent protein mCherry. PAmCherry is non-fluorescent until it is exposed to 350- to 400-nm light. By selecting which cells or cellular regions to activate, you can track cells, organelles, or proteins of interest against a dark background using this photoactivatable fluorescent protein. The activated PAmCherry excitation maximum is 564 nm, and the emission maximum is 595 nm, which allows you to visualize and monitor photoactivated PAmCherry with the same filter sets used for other red fluorescent proteins, such as DsRed variants and mCherry.

Photoactivatable fluorescent proteins such as PAmCherry are particularly useful for determining protein half-life and protein transport pathways because molecules synthesized after activation are not able to fluoresce. Therefore, what you observe is a snapshot of the protein molecules that were present at the time of activation.

PAmCherry subcellular localization vectors are available that target PAmCherry to the cell membrane, mitochondria, actin, or tubulin, respectively. Plasmid and lentiviral N- and C-terminal vectors are also available to create your own PAmCherry-tagged protein of interest.
