Indirect' FISH, based on the enzymatic or immunological detection of tags incorporated into the probe, also continues ... direct visualization of DNA and RNA at the single cell, tissue and whole ...

Team members cut tiny incisions in the fish's bellies to expose their hearts, then applied the probe for 23 seconds ... which was then subjected to RNA sequencing in search of markers indicating ...

If the sequence on the probe exactly matches a counterpart sequence on the target DNA/RNA, the probe latches on. The probe is usually chemically bound to a "reporter" molecule, which produces a signal ...
