Abstract: | If autoradiograms of tritium labeled harlequin chromosomes are stained with the fluorescent dye acridine orange, it is possible to see clearly a fluorescent image of the chromosomes without the silver grains obscuring the image. If fluorescent and bright field microscopy are alternated, the chromosomes and the autoradiogram can be studied repeatedly without having to resort to the study of sequential photographs. The technique is particularly useful for the study of heavily labeled chromosomes. |
