For CGH, genomic DNA was isolated from a muscle of one
preserved male and one preserved female. 1 mg of male and 1 mg
of female genomic DNA were labeled with biotin-dUTP and
digoxigenin-dUTP, respectively, using the Nick Translation Kit
(Roche). Afterwards, the two probes were mixed together with
10 mg of sonicated salmon sperm DNA, co-precipitated overnight
and resuspended in hybridization buffer (50% formamide
