摘要： It is known that rejection of transplant tissue is accompanied by tissue damage of the donor graft. Apart from donor specific proteins and genomic DNA, it is known, that by tissue damage mitochondrial DNA (mtDNA) will be released into the circulation of the recipient. Based on this knowledge it is the object of the present invention to suggest a new method or process to measure the quantity of cell free circulatory mtDNA in bodily fluids as an indicator or marker of tissue damage and to use mtDNA polymorphisms to discriminate between donor and recipient tissue damage in a transplant setting. The method according to the invention is a non-invasive diagnostic procedure characterised by the following steps:

A. Before transplantation
d) Obtaining mtDNA containing material from donor and recipient before transplantation.
e) Isolation of mtDNA.
f) Analysing of the hypervariable regions of the mtDNA for informative polymorphisms which can discriminate between donor and recipient.
B. After Transplantation
c) Obtaining cell free bodily fluids from a patient.
d) Mitochondrial DNA extraction using a commercial procedure. Detection and quantification of donor specific mtDNA in the probe of patient using the donor specific polymorphisms.

摘要： The detection of gross chromosomal abnormalities is a major focus of invasive prenatal diagnosis testing. The object of the present invention is to suggest a new method for the diagnosis of chromosomal and/or genetic abnormalities that is readily amenable to automation and high-throughput screening. This stated object of the invention is achieved by a method, characterised by the following steps:

obtaining DNA or RNA with the genetic test locus,
obtaining DNA or RNA of a control locus and
detecting of the chromosomal and/or genetically determined abnormalities by Real-Time Polymerase Chain Reaction (RT-PCR) analysis, which detects specific nucleic acid amplification products as they accumulate in real-time.
In particular the method is further characterised by a multiplex RT-PCR assay in which amplification of both loci can been simultaneously monitored in the same reaction vessel, by a fluorescently labeled oligonucleotide probe, which eliminates the need for post-PCR processing. It is a preferred object of the invention to provide the method for the detection of trisomy 21 and in this way sequence specific primers for this specific analysis has been designed.
