The length of 44 silver-stained human autosomal pachytene complements was shown to vary from about 300 micrometer to at least 535 micrometer. The lengths of the individual 22 autosomal chromosomes of eight complements representing this interval was measured and the relative lengths calculated. For m

β¦ Synopsis
Human meiotic and mitotic chromosomes were studied with N-N' diethyl pseudoisocyanine stain. Following methylation and oxydation, the staining allowed microscopic observation of slides with both monochromatic light and fluorescence. In addition, stained preparations can be permanently conserved. Preceeded by diverse methods of chromosome denaturation or 5-BUDR incorporation, PIC lends itself to a large number of banding techniques. Cytochemical study of stained chromosomes demonstrated a certain PIC affinity for DNA although tests performed do not exclude the possibility of PIC reaction with certain proteins.

The chromosomes of twenty individuals with normal karyotypes were studied to determine the patterns of staining with the Ag--AS technique. These patterns were shown to be variable from one individual to another, but characteristic and constant within each individual. In addition, one patient with ch
