Abstract: A method for detecting the presence or absence of heteroploidy of fetal chromosomes includes: obtaining a primary amplification products by amplifying chromosomal DNA obtained from a biological sample collected from a pregnant mother; performing multiplex amplification of a plurality of target regions to obtain a secondary amplification product using the primary amplification product as a template; adding a label to both terminals of the secondary amplification product to obtain the labeled secondary amplification product; performing amplification using a primer pair annealing to the label using the labeled secondary amplification product as a template to obtain a tertiary amplification product; and determining the amplification amount and base sequences of the plurality of target regions from the tertiary amplification product. The primary amplification amplifies the total amount of DNA by 6000 to 30000 times, and the secondary amplification step amplifies the total amount of DNA by 3 to 150 times.

Abstract: The present invention provides a noninvasive discrimination method of chromosomal heteroploidy of a fetus, the method including a step of analyzing DNA of a candidate cell of a nucleated red blood cell isolated from maternal blood, in which the fetuses are fetuses classified into any one case selected from monotocous, monochorionic monoamniotic twin fetuses, monochorionic diamniotic twin fetuses, and dichorionic diamniotic twin fetuses based on results of ultrasonic inspections and the number of candidate cells of nucleated red blood cells to be used for analyzing the DNA is optimized based on the classification, and a noninvasive discrimination system of chromosomal heteroploidy of a fetus.

Abstract: In a container including two accommodation parts each accommodating liquid, mixing of the liquids in a case of moving magnetic particles in the liquid accommodated in one accommodation part to the other accommodation part is suppressed. Provided is a container includes a first accommodation part which accommodates a first liquid containing magnetic particles, a second accommodation part which accommodates separated magnetic particles separated from the first liquid, and a second liquid, and a flow passage which allows the first accommodation part and the second accommodation part to communicate with each other, and through which the separated magnetic particles pass, in which the flow passage has a first staircase part including two or more steps from an inner bottom surface of the first accommodation part on a first accommodation part side.

Abstract: A separation device includes: a container that includes a storage portion for storing liquid containing magnetic particles; and a coil that separates the magnetic particles from the liquid by generating a magnetic field through application of current, causing a magnetic force to act on the magnetic particles in a state where the coil stops with respect to the storage portion, and causing the magnetic particles to move from the storage portion against gravity acting on the liquid containing the magnetic particles.
