MagDot 640 PEG
MagDot is a dual-purpose reagent, that combines quantum dots and superparamagnetic iron oxide particles within a patented PEG polymer coating. The pegylated magnetic and fluorescent nanoparticles have very tight size distribution and the amine functional groups on the surface allows conjugation of proteins to label cells of interest.
