New hydrophobic intramolecular charge transfer probes, comprising an aminostyryl and a cyanopyranyl moieties, were developed for sensitive protein quantification in solution. The probes exhibited dramatic increase of fluorescence quantum yields with accompanying blue-shift of the emission when bound to protein–sodium dodecyl sulfate (SDS) complexes. Using this emission enhancement, the synthesized probes were successfully applied for determining protein concentrations in solution.

Highly sensitive new fluorescent stains for proteins in sodium dodecyl sulfate–polyacrylamide gels (SDS–PAGE) were developed by combining an environment sensitive fluorophore and a hydrocarbon tail for improved binding to SDS molecules associated with the proteins. The experimental results showed that these dyes bound to protein–SDS complexes with a concomitant emission increase upon binding.
