PCL(10k)-PEG(5k)-FITC is commonly used to prepare drug loaded nanoparticles for drug delivery or scaffold in tissue engineering. It is an amphiphilic block polymer with a PEG hydrophilic attached to a hydrophobic polycaprolactone (PCL) block. The green fluorescent probe can be used for cell/nanoparticles staining and can be easily traced by fluorescence microscopy. Reagent grade, for research purpose.
