A modified mouse peripheral blood lymphocyte culture system for cytogenetic analysis

Abstract

A detailed methodology is presented for culturing mouse peripheral blood lymphocytes isolated on density gradients and stimulated to divide using either phytohemagglutinin, concanavalin A, or lipopolysaccharide. The techniques described yield more than sufficient numbers of mitotic cells for analyzing sister chromatid exchange, chromosome aberrations, and micronuclei following in vitro or in vivo exposure to chemicals or radiation.
