Figure 2From: Pharmacological Rescue of the Mutant Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) Detected by Use of a Novel Fluorescence PlatformFAP detection of CFTR. HEK293 cells were imaged by confocal fluorescence microscopy. FAP-CFTR WT and CFTR WT EL4-FAP were detected exclusively at the cell surface using the cell-impermeant fluorogen MG-11p (A, C) or at the cell surface and in intracellular compartments throughout the cell with cell-permeant fluorogen MG-ester (B, D). The scale bars indicate 10 µm.Back to article page
