DNA microspectrophotometric study in smear preparations from paraffin embedded tissue.
A DNA microspectrofluorimetric study on smears from cells detached from paraffin embedded tissue is presented. The cellular DNA values of these smears were compared with the cellular DNA values of fresh imprints and paraffin embedded sections obtained from the same tissue. The histograms were similar for fresh imprints and paraffin embedded smears while the DNA values in the sections were notably different. This method appears very suitable for retrospective studies of DNA using microspectrofluorimetry in routine histopathology.
