Fluorescent Probes: Dansyl, Laurdan, and Fluorescein
Product Dansyl based probes are commonly used to modify proteins and amino acids to have fluorescent properties. By modifying these proteins, it makes them much easier to detect for researchers due to dansyl having a high quantum yield and large Stokes shifts. Dansyl probes also see use in heavy metal detection due to the electron transfer effect between the metal and the excited probe. Dansyl
Product Laurdan is a fluorescent probe that is highly sensitive to the polarity of its environment. This sensitivity results in the probe’s emission spectra varying from environment to environment. Due to this key characteristic, it makes Laurdan an excellent tool for studying cell membrane and lipid bilayer dynamics. Laurdan
Product Fluorescein
Fluorescein is a probe that commonly sees uses in ophthalmic procedures as a contrast agent. However, it has many uses outside of the ophthalmic world as well. Fluorescein can be used to differentiate healthy tissue from diseased tissue making it an excellent tool for bioimaging. Many Fluorescein derivates have also proven to be useful to biological researchers. Fluorescein isothiocyanate (FITC) is commonly used for the labelling of protein and antibodies.
