    摘要： A sample preparation procedure for mitochondrial (mt) DNA analysis is described. The present method for isolating mtDNA uses sedimentation techniques for separating erythrocytes from lymphocytes and platelets (crude buffy coat fraction), followed by DNA extraction from the crude buffy coat fraction by boiling in water. This approach improves the yield of mutant DNA, enhancing the sensitivity of subsequent mutation interrogation techniques and allowing for meaningful statistical treatment of the degree of heteroplasmy within the mitochondrial DNA.

    摘要： Methods for covalent attachment of oligonucleotides to solid supports such that substantially all of the oligonucleotides are attached via their 5'-ends are provided. The solid supports with attached oligonucleotides are produced. Thiol-oligonucleotides are attached to bromoacetyl-derivatized polyacrylamide supports, or conversely, bromoacetyl-oligonucleotides are immobilized on thiol-polyacrylamide supports. In a further aspect, bromoacetyl-derivatized oligonucleotides, and polyacrylamide supports with linked oligonucleotides produced by coupling bromoacetyl-derivatized oligonucleotides with thiol-derivatized polyacrylamide solid supports or by coupling thiol-derivatized oligonucleotides with bromoacetyl-derivatized polyacrylamide supports as well as methods for capture of nucleic acids by oligonucleotides attached to polyacrylamide solid supports, either by direct capture or in sandwich hybridization formats are provided.
