| 摘要 |
The present invention relates to a DNA profiling assay comprising the following steps, providing a sample to be analyzed, providing reagents, enzyme and primer-oligonucleotides which are necessary for simultaneous polymerase chain reaction amplification of at least 20 loci, amplifying the loci, detecting the amplification products, wherein the amplification products and the loci to be amplified are characterized by the following features, each locus to be amplified is characterized by at least one deletion-insertion polymorphism known to be present in the population, wherein the two alleles from each locus differ in size by more than 2 nucleotides and less than 100 nucleotides, a first set of at least two amplification products ranging in size from about 20 nucleotides to about 300 nucleotides stemming from at least two different loci carries a first label, a second set of at least two amplification products ranging in size from about 20 nucleotides to about 300 nucleotides stemming from at least two different loci carries a second label, a third set of at least two amplification products ranging in size from about 20 nucleotides to about 300 nucleotides stemming from at least two different loci carries a third label, label one, label two and label three are each different fluorescent labels which can be differentiated and simultaneously detected by a multi-colour detector in combination with, e.g. a DNA sequencing device. |
