1. Example fluorescence microscopy traces of fluorescein uptake in the presence and absence of a representative OAT inhibitor, methotrexate.
Example fluorescence microscopy traces of fluorescein uptake in the presence and absence of a representative OAT inhibitor, methotrexate. During an uptake trial, the signal trace shows an initial rapid increase in fluorescence due to the change-out of chamber with fluid containing FL (a), followed by a slower increase representing accumulation in the tubule (b).
