Forensic analysis of DNA from bone can be important when investigating cases involving violent crimes or missing persons. To remove the potential presence of commingled remains and to eliminate contaminants that interfere with forensic DNA analysis, the outer surface of the bone fragment must be cleaned—a labor‐intensive and time‐consuming step. A simpler, more reliable processing method is needed. This study evaluates two methods for processing bone specimens before their DNA is isolated: mechanical sanding and enzymatic trypsin.
Low copy number (LCN) typing is a general technique used for analyzing low-quantity DNA samples. Short tandem repeat (STR) testing on aged and extremely limited samples, such as “touch DNA” samples, has increased over the past decade. Samples with low quantities of template DNA are typically subjected to exaggerated stochastic effects during the polymerase chain reaction (PCR) that impact the reproducibility and reliability of DNA typing results.
