Takara tdTomato fluorescent protein

tdTomato is an exceptionally bright red fluorescent protein—6X brighter than EGFP. tdTomato`s emission wavelength (581 nm) and brightness make it ideal for live animal imaging studies. The tdTomato fluorescent protein is as photostable as mCherry (Shaner et al. 2004). Sequence mutations were introduced into a monomeric variant of DsRed through directed evolution by the Tsien lab in order to produce tdTomato.

The tdTomato fluorescent protein is as photostable as mCherry (Shaner et al. 2004). Sequence mutations were introduced into a monomeric variant of DsRed through directed evolution by the Tsien lab in order to produce tdTomato. This very bright red fluorescent protein was made even brighter by creating a tandem dimer version, the tdTomato fluorescent protein. Because tdTomato forms an intramolecular dimer, it is considered monomeric (Shaner et al. 2004).
