Representational difference analysis (RDA) is a highly sensitive technique for the identification of differences between complex deoxyribonucleic acid samples. RDA is based on polymerase chain reaction amplification in combination with multiple rounds of subtractive hybridization and can be used for the identification of unknown pathogens, genetic lesions in cancer and polymorphic markers linked to a trait without the use of a preexisting map, as well as for the identification of differentially expressed genes.
