Capillary transfer in southern blotting
WebSouthern blot . Notes: The Southern blot is the most common way to analyse restriction endonuclease-digested DNA to find specific sequences of interest. It uses the fact that denatured nucleic acids will bind to nitrocellulose or nylon membranes. DNA fragments are separated by size on a gel, then transferred to the membrane by capillary ... WebIn simultaneous transfer to two membranes, when the target DNA fragments are present in high concentration (e.g., in restriction digests of cloned DNAs), the capillary method can …

WebMay 1, 2001 · 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. Web2. Transfer methods: The Southern blot can be generated by a range of transfer methods, including vacuum or electrophoretic blotting, in addition to the original capillary method ().The prime advantage of vacuum blotting is speed: gel pretreatment and transfer can be completed in only 40 min for a wide range (<1 – >20 kb) of DNA fragment sizes.
