摘要（PubMed 原文节选）
The identification and age estimation of body fluid stains found at crime scenes provide crucial information for reconstructing events and narrowing down the potential suspect pool. In this study, we developed a multiplex methylation SNaPshot system containing seven age-related CpGs (AR-CpGs) and two semen-specific CpGs that enables simultaneous acquisition of information on donor age and sample type from a single reaction. Four candidate AR-CpGs derived from previous in-house screening (cg17791346, cg06880412, cg25093603, and cg06966678) were incorporated into system and showed Pearson correlation coefficients (R) ranging from 0.527 to 0.717 with chronological age. The performance of the mu…
