pubmed:abstractText |
We wish to report a novel method for visualizing large unilamellar vesicles loaded with a fluorescent dye and for monitoring changes in the size distribution as well as state of aggregation of such dye-loaded liposomes. In addition, we demonstrate that this method can be used to distinguish between all-or-none release of dye and graded release of dye from individual vesicles. Using this technique, we have characterized complement-mediated release of carboxyfluorescein from large unilamellar vesicles and have found that C5-8 complexes mediate a graded release of dye while C5-9 complexes cause an all-or-none release. Furthermore, complement appears to preferentially attack the medium to larger-sized vesicles in our population of large unilamellar vesicles while smaller vesicles appear to be selectively spared.
