<p>Provided is a method for isolating and obtaining pure and complete fetus genome DNA, comprising the following steps: isolating a nucleated erythrocyte from the maternal (pregnant woman) peripheral blood, identifying the individual hereditary feature subtype of the mother and/or father of the fetus; conducting high fidelity whole genome DNA amplification on the signal cell isolated from the nucleated erythrocyte; identifying the individual hereditary feature subtype of the fetus according to the laws of hereditary, and determining a fetus-originating genome DNA. The fetus-originating pure whole genome DNA provided by the present invention lays a material foundation for prenatal heredity diagnosis.</p> |
