Fluorescent Probes Fluorescent Dye

Fluorescent probes absorb light at a specific wavelength and emit light of a different, typically longer, wavelength. This process is known as fluorescence emission. Fluorescence is safer to use and does not require radiological controls. Because fluorophores do not overlap, several fluorescent molecules can be used simultaneously.

Fluorescent molecules can be attached to a target molecule and act as a marker for analysis with fluorescence microscopy.  Often times, the poor water solubility of many organic fluorescent molecules limits their biological applications.  Polyethylene glycol modified fluorecence dye have improved aqueous solubility and expand the scope of the fluorophore applications.

Conjugating a desired fluorescent probe with a defined PEG length using mono dispersed polyethylene glycol facilitate the optimization process in fluorometric applications.

AxisPharm offers a diversified collection of fluorescent dye probes that incorporate mono dispersed PEG with various functional groups such as azide, alkyne, TCO, tetrazine, etc. We also provide custom synthesis of functionalized fluorescent dye probes at competitive prices.
