Description

A kind of DNA testing reagent for sample investigation and primer special
Technical field
The present invention relates to biological technical field, particularly relate to a kind of DNA testing reagent for sample investigation and primer special.
Background technology
DNA inspection technology especially (Short Tandem Repeats) STR detection technique, since 20th century, the mid-80 came out, has all played huge effect in criminal, civil case, large-scale catastrophic failure (as: U.S.'s the September 11th attacks, Indonesia's tsunami, Wenchuan violent earthquake) and mass unexpected incident.STR (STR), also known as microsatellite DNA (microsatellite DNA), STR detection technique is mainly by detecting the polymorphism in these specificity STR sites, after the information obtaining multiple corresponding STR site, carry out the parallel comparison of multidigit dot information, thus achieve individual recognition and paternity identification.STR detects with its distinctive technical superiority, is focus and the core of medicolegal genetics research in decades always, and is widely used in multiple fields such as medical jurisprudence individual recognition and paternity test.Forensic DNA typing standard committee of European Union is thought, although new technology and new genetic marker continue to bring out, within period quite long from now on, STR will remain topmost human specific genetic marker.
Human Y-chromosome is not recombinated with other karyomit(e) in genetic process, and sequence structure feature can stably be handed down from father to son and by the male sex peculiar, there is paternal inheritance feature.Male participation is had in most of case of violence and all rape offenders.Therefore, the effect of Y-STR in forensic science manifests gradually.When there is no the paternity determination of father, utilizing the paternal inheritance feature of Y chromosome str locus seat (Y-STR), can be identified by paternal relative.In mixed stain qualification, when particularly cannot be separated by two-step approach, Y-STR has more advantage.In gang-rape case, Y-STR is for determining that criminal's number also has great role.In addition, because Y-STR has patroclinous feature, the colony of not agnate, different areas, the distribution of Y-STR also exists otherness, can disclose the race of suspect, residence or even surname to its somatotype.
In recent years, along with the develop rapidly of Protocols in Molecular Biology, increasing Y-STR is developed and utilizes.1997, the first time such as Prinz established Y-STR composite amplification system, called after Quadruplex I, marks DYS19, DYS389I, DYS389II and DYS390 respectively, and done forensic application Journal of Sex Research with two kinds of fluorescence JOE and FAM.American AB I (Applied Biosystems) company is proposed Y-Filer test kit, comprises 17 Y-STR sites such as DYS456, DYS389I, DYS389II, DYS390, DYS458, DYS19, DYS385, DYS393, DYS391, DYS439, DYS635, DYS392, YGATA-H4, DYS437, DYS438, DYS448.Promega company of the U.S. also develops the PowerPlex Y test kit comprising 12 Y-STR sites such as DYS391, DYS389I, DYS439, DYS389II, DYS438, DYS437, DYS19, DYS392, DYS393, DYS390, DYS385a/b.These Y-STR test kits play increasing effect in forensic dna inspection field.
Along with the development of micro-Y chromosome STR inspection technology, its range of application has the trend expanded further, as the quick investigation of Y-DNA database establishment and extensive sample.But current existing Y chromosome DNA detection reagent really encounters new problem in application process.Because Y-STR has patroclinous feature, under normal circumstances, the STR genotyping result that the sample of same family obtains is identical.Just there are two subject matters in this, one is to determine whether the sample with identical Y-STR somatotype exists the phenomenons such as sample cross contamination in a large number in extensive checkout procedure; Two is after determining family, also needs again to carry out euchromosome STR inspection, to realize precise alignment to whole samples of corresponding family.This will greatly increase the workload of reviewer, reduces overall inspection efficiency, increases inspection cost.
