[Studies on the cytotoxicity of poly-L-arginine, poly-L-lysine and DEAE-dextran in L-cells and mouse embryonic fibroblasts].

Cellular insulin uptake is influenced by poly-L-arginine, poly-L-lysine and DEAE-dextran. In this study it is asked for the mechanisms of these influences as well as for the cytotoxicity of different concentrations of these substances. The experiments aim to contribute to the knowledge on toxic concentrations of polycations.
