Investigator DIPplex Kit

同时扩增30个插入/缺失多态性位点和性别鉴定基因

Features

  • 可选标记物的独特试剂盒
  • 扩增子长度约为160 bp,十分适合降解的DNA样本
  • 适用于灾难受害者身份鉴定和人类学研究
  • 提供DIPSorter免费软件,简便的解释结果

Product Details

Investigator DIPplex Kit可实现30个插入/缺失多态性位点(也被称为INDELs)和性别鉴定基因的同时扩增,是基于STR和SNP的人类身份鉴定之外的一种方法。其扩增子最长约为160 bp,因此适合于分析高度降解的DNA。使用优化的染料BT5 Matrix进行分析校准。

Performance

使用GeneAmp 9700热循环仪(标准模式)和ABI PRISM 310、ABI PRISM 3100和Applied Biosystems 3130 Genetic Analyzers对Investigator DIPplex Kit进行验证和评估。

在标准条件下,DNA的推荐使用量为0.35 ng.。内部的验证显示使用0.2–0.5 ng获得稳定平衡的结果,而使用<0.1 ng DNA获得可靠的结果。

Investigator DIPplex Kit相对标准的以STR-和SNP-为基础的DNA图谱制备有明显的优势,包括不存在自显峰和极短的扩增子(低于160 bp)。

Principle

人类身份鉴定普遍基于短串联重复序列(STRs)的分析或单核苷酸多态性(SNPs),取决于检测需求或样本品质。Investigator DIPplex Kit采用另一种人类身份鉴定方式,进行等位基因缺失/插入多态性分析(DIPs,也称为INDELs)。

Procedure

30个等位基因DIP位点和Amelogenin可同时在一个单独的PCR中得到扩增,并有四种染色剂标记。参见下表“技术规格”以获得更多信息。

FAQ

3196 - What is the DIPsorter Freeware?

DIPSorter Freeware has been developed as a utility application for the Investigator DIPplex Kit. Its function is to re-sort genotype data of biallelic deletion or insertion markers — the so-called DIPs.

DIPSorter Freeware enables the import of Genotype Table text files exported from GeneMapper® ID, GeneMapper ID-X, or Genotyper® software and displays them as sorted genotype tables. Generated data can be printed and exported to *CSV and *PDF files.

3194 - What DNA fragment sizes are required for the Investigator DIPlex kit?

The Investigator DIPlex kit produces short amplicon lengths (max. 150 for 30 DIPs) so that DIPplex can be used for identification of very challenging samples (highly degraded).To get a full DIPplex profile, you need DNA fragments of at least 160 bp. If your sample contains fragments of max.75 bp, you will not get any positive results. Usually, degraded samples show varying average fragment sizes. Therefore, a positive result is dependent on the quality of each sample.

3195 - Where can I find the Population Data for the Investigator DIPlex kit?
The Population data excel file can be found on the “Resources tab” on the product webpage.
3198 - What is the optimal DNA concentration for the Investigator DIPlex Kit?
The optimum DNA input range is between 200-500 pg. The quoted detection limit is 100 pg (full profile with one assay), but reliable results can be obtained with less then 100 pg. For higher amounts of input DNA, consider adjusting the PCR cycle number.
