摘　　要：目的探讨直接扩增法对软骨STR检验的有效性,以提高灾难受害者身源鉴定工作效率。方法采用Power Plex~21试剂盒对88份软骨进行直接扩增法检验,同步进行磁珠法比较分型结果。结果 88份软骨检材中,直接扩增法与磁珠法均成功检出84份检材的STR基因型,两者分型结果完全一致。结论Power Plex~21试剂盒直接扩增法可以应用于软骨STR分型检验,且操作简便、快速,在重大灾难事故身源鉴定中具有很好的应用前景。Objective To explore the effectiveness of direct amplification for the STR analysis of cartilage, and to accelerate the effectiveness of disaster victim identification. Methods Eighty-eight cartilage samples were directly amplified by Power Plex 21 kit, and the results of genotyping were compared with that obtained by the magnetic beads method. Results In 88 cartilage samples, the STR genotypes were successfully detected from 84 samples by direct amplification and magnetic beads method, and both the results of genotyping by two method were consistent. Conclusion Direct amplification with PowerPlex21 kit can be used for STR genotyping of cartilages. This method is operated easily and promptly,which has a potential application in the individual identification of mass disasters.
