Canine cDNA is an essential molecular resource for investigating gene expression, functional genomics, and comparative biomedical research in the domestic dog (Canis lupus familiaris). Generated by reverse transcription of messenger RNA (mRNA), cDNA captures the expressed coding transcript repertoire of the sampled tissue or cells while excluding intronic sequences. Consequently, canine cDNA is well suited for analyses of tissue-specific gene expression, transcript characterization, and molecular cloning. Because the dog shares numerous physiological, genetic, and pathological similarities with humans, canine models play an important role in translational research, particularly in oncology, neurology, cardiology, immunology, and inherited diseases. The availability of a high-quality annotated canine genome has further strengthened the use of canine cDNA in comparative genomics and molecular biology studies.
