Various factors involved in the production of "Q-bands" have been studied. It was found that a Zeiss standard WL fluorescent microscope required a shorter exposure time for photography as compared to a Zeiss photomicroscope. The minimal exposure time was obtained when the standard WL microscope was equipped with a UV light source containing a DC powered mercury burner and a concave mirror. Further, the pH and type of water used in the staining, washing and mounting of the slide were also important factors in producing clear and well differentiated "Q-bands". It also appears that the factors involved in the production of "Q-bands" effect the enhancement or quenching of fluorescence by poly d(A-T).poly d(A-T) and salmon sperm DNA or poly dG∙poly dC respectively. This preliminary report also suggests that DNA or polynucleotides with a specific base sequence may play an important role in Q-banding patterns on chromosomes.

Distinct Banding Pattern

A simple technique is described for differential staining of human chromosomes with Giemsa. The procedure involves DNA denaturation with a methanol-acetic acid fixative, and subsequent annealing using a saline solution. This technique has a number of advantages over quinacrine fluorescence, and gives a more distinct banding pattern. It is a rapid, inexpensive procedure and can be done with existing equipment and material in most cytogenetic laboratories.
