Capillary transfer in southern blotting
WebMay 1, 1998 · This appendix describes Southern blotting via upward capillary transfer of DNA from an agarose gel onto a nylon or nitrocellulose membrane, using a high-salt transfer buffer to promote binding of DNA to the membrane. With the high-salt buffer, the DNA becomes bound to the membrane during transfer but not permanently immobilized. WebIn Southern blotting, DNA is digested with one or more restriction enzymes, and the resulting fragments are separated according to size by electrophoresis through a …

The genomic DNA is digested with either one or more than one restriction enzyme, then the DNA fragments are size-fractionated by gel electrophoresis. Before the DNA fragments are transferred to a solid membrane which is either nylon or nitrocellulose membrane it is first denatured by alkaline treatment. After the DNA fragments are immobilized on the membrane, prehybridization methods are used to reduce non-specific probe binding then the fragments on the membrane ar…
