title: Extraction and characterization of circulating plasma DNA from patients with pulmonary embolism.
abstract: Circulating DNA has been extracted from plasma of 6 patients with pulmonary embolism; it appears of low molecular weight (about 400 base pairs) and of uniform size; its staining sensitivity to ethidium bromide suggests it is mainly double stranded. DNA circulates linked with proteins.
