Photoactivatable red fluorescent protein PA-TagRFP

- Monomer, successful performance in fusions
- Non-fluorescent before photoactivation
- Irreversible photoactivation to a red fluorescent form by UV-violet light irradiation
- High brightness and photostability
- Recommended for super-resolution imaging

Available variants and fusions

Variant	Description	Related vector	Cat.#
Humanized PA-TagRFP	PA-TagRFP codon usage is optimized for high expression in mammalian cells [Haas et al., 1996], but it can be successfully expressed in many other heterological systems.	pPA-TagRFP-C	FP811
		pPA-TagRFP-N	FP812
PA-TagRFP-tubulin fusion	Human α-tubulin is fused to the PA-TagRFP C-terminus. When expressed in mammalian cells, this fusion provides red fluorescent labeling of α-tubulin in living cells.	pPA-TagRFP-tubulin	FP814
PA-TagRFP-H2B fusion	Human histone H2B is fused to the PA-TagRFP N-terminus. When expressed in mammalian cells, this fusion provides red fluorescent labeling of histone H2B in living cells.	pPA-TagRFP-H2B	FP815
