The disclosure is directed to a method for comparing a first tissue sample and a second tissue sample. The method includes degrading hybrid duplexes from a solution to leave at least one of a first set of uncomplexed RNA strands derived from the first tissue sample and a first set of uncomplexed cDNA stands derived from the second tissue sample. The solution includes the hybrid duplexes, the first set of uncomplexed RNA strands and the first set of uncomplexed cDNA strands.
