Fluorescein-labeled deoxyribozymes undergo site-specific hydrolysis when exposed to Zn 2+ outside of the liposomes. (b) Representative TEM images of sorted liposomes containing deoxyribozymes.
WebOur liposome leakage assay (Fig. 24) probes several facets of leakage competence (13). Briefly, a fluorescent dextran is encap-sulated within a large unilamellar liposome. The size of this dex-tran (70 kDa) is such that it remains trapped in the liposome lumen upon exposure to leakage-inducing peptides. Leakage competence
