In situ hybridization, in situ transcription, and in situ polymerase chain reaction. [PDF]

open access: yesScanning microscopy. Supplement, 1996
In situ hybridization, in situ transcription, and in situ polymerase chain reaction (PCR) are techniques used to detect DNA and RNA sequences within a cell or tissue structure. These three in situ methodologies employ the principles of recombinant DNA to form double-stranded hybrids of DNA-DNA, DNA-RNA, or RNA-RNA. The essence of in situ hybridization (
