CHEMILUMINESCENT METHOD FOR THE QUANTITATION OF HUMAN DNA

摘要

RAN 4095/94 The present invention provides methods and reagents for the estimation of the quantity of human DNA contained in a sample. Immobilized sample DNA is hybridized to a biotinylated oligonucleotide probe that hybridizes to a human genomic or mitochondria DNA. sequence. The subsequent binding of streptavidin-horseradish peroxidase to the bound probe allows for chemiluminescent detection using a luminol-based reagent and X-ray film. In addition, the present invention provides methods and reagents to assess the quality of DNA contained in a sample. The sample is first size fractionated by agarose gel electrophoresis, and then immobilized, hybridized to a biotinylated oligonucleotide probe, and detected using the chemiluminescent method as used in the quantity estimation methods of the present invention.
