Overview. Patient Information. WebApr 7, 2016 · Circulating cell-free DNA released from apoptotic cells is uniformly truncated into 185- to 200-bp fragments [ 79, 80 ], whereas cell-free DNA released from necrotic tumor cells varies in length, which may lead to elevation of DNA with long fragments in plasma [ 30] or serum [ 81 ].
