· Comparative Genomic Hybridization (CGH) CGH is a molecular Cytogenetic method of screening a tumor for genetic changes. The alterations are classified as DNA gains and losses and reveal a characteristic pattern that includes mutations at chromosomal and subchromosomal levels. This protocol gives detailed procedures on CGH as follows:
Metaphase chromosome preparation
DNA preparation by cryostom tissue dissection
DNA labeling by nick translation
Hybridization
DNA detection
Image capture
Image analysis
DAPI chromosome identification
