The ELISA of cellular DNA fragmentation is a sandwich ELISA that measures apoptosis by quantitating the fragmentation and/or release of BrdU-labeled DNA. The commercial kit (Roche) can detect DNA fragments in the cell-free supernatants from cultured cells or cytoplasmic lysate of apoptotic cells prelabeled with BrdU...

As usual, the situation is not so clear-cut, and the requirement for Ca for the DNA cleavage observed in apoptosis is not universal. DNA fragmentation precedes apoptosis in PC 12 cell cultures and in primary cultures of neurons, but this does not require an elevation in [Ca ] (Batistatou and Green, 1991, 1993 Edwards and Tolkovsky,...
