A DELFIA® time-resolved fluorescence cell-mediated cytotoxicity assay performed on the PHERAstar
Application Note Aug 05, 2009
A europium based time-resolved fluorescence cytotoxicity assay was used to study the loss of membrane integrity of target cells. For that cells are loaded with a fluorescence enhancing ligand that penetrates the cell membrane quickly and is hydrolized to form a hydrophilic ligand that is released from cells only after cytolysis. The data obtained with BMG LABTECH´s PHERAstar shows that estrogen dramatically reduces cell induced by natural killer cells.
