Lysis buffer is intended for use in cell-mediated DELFIA cytotoxicity assay (for the determination of the maximum release). The product forms part of the AD0116 DELFIA® EuTDA Cytotoxicity Reagents pack, and is also available as a separate product. It can also be used in cell based TruPoint™ Caspase assays.

DELFIA cytotoxicity assays offer a non-radioactive method to be used in cell mediated cytotoxicity studies. The method is based on loading cells with an acetoxymethyl ester of a fluorescence enhancing ligand. After the ligand has penetrated the cell membrane the ester bonds are hydrolyzed within the cell to form a hydrophilic ligand, which no longer passes through the membrane. After cytolysis the released ligand is introduced to a europium solution to form a fluorescent chelate. The measured signal correlates directly with the amount of lysed cells.
