This paper describes a study of the role of certain cations in the alkaline pretreatment step used in the CT technique for chromosome band formation. Treatment of human chromosomes with ammonium bases or with the hydroxides of the monovalent alkali metals Na, K, or Li resulted in their rapid disinte

We present a classification for secondary constriction (qh) regions with C-banding technique in chromosomes 1, 9, and 16 by means of comparing them to the short arm of chromosome 16. It is simple and convenient and can be used routinely. It can be incorporated into the modified Paris nomenclature sy
A new technique is described which produces spiralization of human metaphase chromosomes. The important feature is heat followed by trypsin treatment. By varying conditions, it is possible to produce bands, spirals and intermediate stages. This provides a new approach to the understanding of banding
