title: A rapid and simple sandwich-method used for chromosome analysis from small fetal and adult biopsy specimens.
abstract: A new Sandwich-Method is described which uses aborted material and yields a high frequency of metaphases. Chromosome studies may be performed after 7--8 days without subculturing. It is possible to freeze the original tissue for later cell culture.
