Multidrug Transporter Substrates Fluorescent Probes and Dyes

ATP-binding cassette (ABC) transporters form one of the largest groups of paralogous protein families that have a wide diversity of functions and substrates. Specificity has been shown for small and large molecules, highly charged molecules and highly hydrophobic molecule systems such as that for polysaccharides. Multidrug transporters (MDRs) are a specific type of ABC transporter and are commonly overexpressed in cancer cells.

P-glycoprotein (P-gp, ABCB1, MDR1) is a well-characterized human ...
