AcknowledgementsWe thank Dr. H.-D. Zucht (Niedersächsisches Institut für Peptid-Forschung, Hannover/Germany) for his help in measuring gene amplification. (E)-5-(2-bromovinyl)-2´-deoxyuridine (BVDU) was a gift from Berlin-Chemie/Berlin/Germany. Friend mouse erythroleukemia cells, line F4-6 were kindly provided by Prof. W. Ostertag (Heinrich Pette Institute/Hamburg/Germany). The mdr1 probe pHDR5A was generously provided by Dr. M. M. Gottesman, National Cancer Institute, NIH, Bethesda, Md., USA; the human b-actin cDNA probe was kindly provided by Dr. T. Braun, Institute of Biochemistry and Biotechnology, University of Braunschweig, Germany).
