Application

Maleimidourea-rhodamine-110 trimethyl lock may be used:
  • Rhodamine 110 based pro-fluorophore activated by esterases in cells.
  • Maleimide functionalized for conjugation to thiolates of small molecules or biomolecules.
  • High signal to noise ratio compared to fluorescein diacetate.
  • Able to fluorescently monitor passage of biomolecules into cells.

Fluorescent molecules are essential for basic research in the biological sciences and have numerous practical applications. Herein is described the synthesis and use of a new class of latent fluorophores based on a novel design element, the trimethyl lock, that

Traditional small-molecule fluorophores are always fluorescent. This attribute can obscure valuable information in biological experiments. Here, we report on a versatile "latent" fluorophore that overcomes this limitation. At the core of the latent fluorophore is a derivative of rhodamine in
