PG - 289-91 AB - Lymphocytes respond to chemical or pathological challenges by synthesizing episomes or extrachromosomal DNA (eDNA). Phytohemagglutinin (PHA) is a mitogen for T lymphocytes and can stimulate the increased production of episomes as well as the release of eDNA, interleukin-2, and other factors. However, the origin of this eDNA is largely unknown. To confirm the observation on the localization of an antibody directed against a 23-kb segment of bull acrosomal DNA in cultured human lymphocytes, we performed analyses by fluorescence in situ hybridization (FISH) using the same DNA as a molecular probe.
