Revvity Delfia Eutda Cytotoxicit

Revvity DELFIA time-resolved fluorescence cell cytotoxicity assays offer a non-radioactive method to Chromium 51, for use in cell-mediated cytotoxicity and antibody-dependent cell cytotoxicity (ADCC) 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. - REVPFZ (Additional S&H Or Hazmat Fees May Apply)
