Solid Phase Extraction Of Mammalian Cell Mitochondrial Dna And Its Electrophoretic Separation In Agarose Gels, Theresa Brick-Miller

Biological Sciences Theses & Dissertations

An improved and efficient electrophoretic procedure for the isolation of mitochondrial DNA (mtDNA) is described. The solid phase extraction procedure for the isolation of mtDNA involves embedding as few as 200,000 Ehrlich ascites tumor cells into a block of agarose, digestion of cellular membranes by detergent action and subsequent electrophoretic separation of nucleic acids in agarose gels. Genomic DNA remains in the original block of agarose while the mtDNA migrates in the separation gel to a position equivalent to that obtained for mtDNA isolated by traditional procedures.

The efficacy of a large number of detergents, agarose concentrations, embedding conditions, embedding …
