ENRICHING A SAMPLE OF CIRCULATING CELL-FREE NUCLEIC ACIDS

摘要

A method of enriching a sample of circulating cell-free DNA for DNA derived from a foetus or from a tumour includes carrying out amplification of DNA such that amplification of longer DNA molecules is discriminated against. This results in preferential amplification of foetal or tumour DNA, which can then be analysed using, for example, array comparative genome hybridisation.
