DNA Probe Labels for Detecting Targets

Description

DNA probes are short DNA fragments with a reporter tag attached so they can be detected or purified. They bind to matching nucleic acid sequences by complementary base-pairing. That binding helps researchers recover or identify specific regions of DNA.

Several reporter tags are commonly used to l...

Transcript

Imagine an experiment where the goal is establishing the presence or absence of a specific gene in a bacterial genome. How might such a small nucleic acid sequence be detected within the complex genomic DNA?

DNA probes can be used to achieve this - these are single-stranded DNA molecules that are complementary to the target nucleic acid s...
