How southern blot probes are made
NettetProbe Labeling. Specific sequences in the restriction pattern on a Southern blot can then be identified by hybridization with a DNA probe. A probe is a piece of DNA identical (or very similar) to a sequence of interest. In order to locate a specific DNA sequence by hybridization, the probe is labeled with a reporter group.
