Please help! I am having trouble contacting the authors of a publication in which the plasmid REP81X, (TATA box mutation in nmt1 promoter), is described. Basi G, Schmid E, Maundrell K, Gene; 123: 131-136, (1993).Does anyone know how I can get my hands on this vector? I hope my problem will be solved!! Thanks Karen Dept of Genetics Nottingham UK
