Abstract
Direct label probe compositions which counterstain genomic DNA are provided that comprise mixed DNA segments which are covalently bound to fluorophore groups through linking groups. The mixed DNA segments are derived from the total genomic DNA of a multi-chromosomal organism, especially man, and the segment mixture is approximately representative of such total genomic DNA. These probe compositions can be used concurrently or sequentially with other probe compositions. Instead of intercalating with DNA as in prior art chemical counterstains, these probe compositions hybridize with complementary segments that are present in the genomic DNA of a specimen.
