Fluorescence In Situ Hybridization of DNA Probes on Mitotic Chromosomes of the Mexican Axolotl.

ABSTRACT

Fluorescence in situ hybridization (FISH) is used extensively for visual localization of specific DNA fragments (and RNA fragments) in broad applications on chromosomes or nuclei at any stage of the cell cycle metaphase, anaphase, or interphase. The cytogenetic slides that serve as a target for the labeled DNA probe might be prepared using any approach suitable for obtaining cells with appropriate morphology for imaging and analysis. In this chapter, we focus on the application of molecular cytogenetic methods such as DNA labeling, slide preparation, and in situ hybridization related to cells from Mexican axolotl.
