Abstract excerpt
BACKGROUND: Cross-contamination is a persistent problem in the establishment and maintenance of mammalian cell lines. The observation that the cell lines PC-3, ALVA-31, and PPC-1 all have a homozygous deletion of the alpha-catenin gene prompted us to investigate the uniqueness of these and several other widely used prostate carcinoma cell lines. METHODS: The genetic backgrounds of the putative human prostate cell...
