Imaging small molecule-induced endosomal escape of siRNA

Therapeutic siRNA becomes trapped in endosomes, limiting its efficacy. Here the authors use fluorescently-tagged galectin-9 as a biosensor for membrane damage to monitor endosomal escape of cholesterol-conjugated siRNA following treatment of small molecule membrane-destabilising drugs.
