由于ＳＴＲ位点扩增片断较短，对降解ＤＮＡ能有效分析，已成为目前法医ＤＮＡ检验常用技术。特别是ＳＴＲ位点复合扩增技术的推广应用，由于采用了等位基因阶梯，按国际通用的分型标准，使不同时间、不同实验室的检验结果可以比较，从而可对多宗或系列案件的串并提供线索和科
Due to the shorter amplification fragments of STR loci, effective analysis of degraded DNA has become the common technology of forensic DNA testing. Especially the popularization and application of STR amplification by STR, because of adopting the allelic ladder, according to the international common typing standard, the test results of different time and different laboratories can be compared, so that multiple or series of cases The string and provide clues and sections
