This unit provides detailed methods and material descriptions for in situ hybridization following in situ amplification of DNA or RNA by PCR. It includes all essential components of the techniques, including variations suitable for different kinds of tissue and cell preparations. Planning, controls, and critical parameters for the amplification steps are discussed.

D016133	Polymerase Chain Reaction	In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.
