Lipid vesicles containing labeled species and their analytical uses

摘要

Vesicles comprising a matrix of lipid membranes prepared from lipid materials are useful in biomedical studies and immunoassays. A labeled species is encapsulated within the vesicles and released when the vesicles are lysed with a surface active agent. The outer surface of the vesicles is essentially free of the labeled species. Immunoassays can be carried out in solution or with a dry analytical element.
