Description:
M1202 is a new 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. 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.
