Detection of DNA in Agarose Gels Protocol - http://www.cshprotocols.org/cgi/content/extract/2006/2/pdb.prot4022

Category: Nucleic Acid Electrophoresis Protocols: DNA Electrophoresis Protocols: DNA Electrophoresis in Agarose Gels Protocols

The most convenient and commonly used method to visualize DNA in agarose gels is staining with the fluorescent dye ethidium bromide. Ethidium bromide can be used to detect both singleand double-stranded nucleic acids (both DNA and RNA). However, the affinity of the dye for single-stranded nucleic acid is relatively low and the fluorescent yield is comparatively poor. - [Read Detection of DNA in Agarose Gels Protocol]

The first part of the isolation procedure is a flotation through a continuous iodixanol gradient; this gradient is essentially a resolving gradient in which the caveolin-rich vesicles are concentrated in the top third of the gradient, while the predominantly caveolin-poor vesicles band in denser regions. A second discontinuous gradient is essentially a concentration gradient to band the caveolin-rich vesicles sharply at an interface. - [Read Purification of Caveolae Membranes from a Plasma Membrane Fraction of Cultured Cells and Tissues]
