Chromosome banding patterns

Homogeneously Staining Region - A region of a chromosome that lacks the typical chromosome banding pattern. It can be produced by gene amplification.

Chromosomes with fluorescent signals can be counterstained with Hoechst 33258 as described below. However, banding patterns produced by the fluorescent DNA stains are often difficult to compare with the published polytene chromosome-banding patterns. We find it more convenient to simply use phase contrast to correlate the fluorescent signal with the corresponding chromosome bands.
