  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.

  针对十二烷基硫酸钠-聚丙烯酰胺凝胶（SDS-PAGE）中的蛋白质开发了高灵敏度的新型荧光染色剂，该染色剂结合了对环境敏感的荧光团和碳氢化合物尾部，以改善与蛋白质相关的 SDS 分子的结合。实验结果表明，这些染料与蛋白质-SDS 复合物结合后，发射率随之增加。
