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. Nettet1. jul. 2024 · Southern transfer and hybridization are used to study how genes are organized within genomes by mapping restriction sites in and around segments of genomic DNA for which specific probes are available.

How can I design a probe for southern blotting?

NettetThe Southern blot (named for its inventor, E. M. Southern) is a method for hybridizing one or more labeled DNA probes to a large number of DNA fragments and discriminating among them. The procedure depends on the ability of denatured DNA single strands to bind tightly to nitrocellulose under certain conditions.
