Description: Long-wavelength fluorescent labeling agent for cis-diols (sugars) at high pH values on cell surfaces and in vitro for carbohydrate determination in glycoproteins and for HPLC analysis of sugars.
Application: This labeling agent can be used in conjunction with other fluorophores, for multiplexed analysis, in fluorescence energy transfer (FRET) studies or in a high-throughput format (EX 520/ EM544). The fluorescence emission of the eosin labeled compound can exhibit environment sensitive fluorescence emission properties. The eosin derivatives can also exhibit phosphorescence with an emission maximum at ~680 nm. See the references below for more information.
