title: Excretion of newly synthesized DNA by tonsil lymphocytes.
abstract: The main part of newly synthesized DNA is preferentially released in vitro both by non-stimulated or phytohemagglutinin-stimulated tonsil lymphocytes. Freshly isolated cells excrete DNA faster than phytohemagglutinin-stimulated ones. The acid-precipitable 3H-thymidine lost can be accounted for in the culture medium as labeled, double stranded DNA isolated on hydroxyapatite column.
