Fluorescein-PEG7-Methyltetrazine is a xanthene dye with excitation/emission maximum of 494/517 nm and a terminal tetrazine group. The terminal methyltetrazine enables fast click reactions with TCO (trans-cycloctene). Hydrophilic PEG spacer increases solubility in aqueous media and reduces steric hindrance during binding.
