Abstract

Acetic acid (pH 2.0) treatment denatures chromosomal DNA in situ. Following in situ hybridization cellular and chromosomal morphology is well preserved. For AT-rich DNA sequences the final efficiency of the subsequent hybridization reaction is comparable to the routinely employed NAOH denaturation method, and although there is some discrimination against denaturation of high GC-rich DNA sequences it is less marked than with HCl.
