Current research in the biomedical field has illustrated how cell lines used as reference standards can change over time and, more importantly, can affect research and diagnostic results obtained from these cell lines. With the use of increasingly sensitive and highly resolving technologies (e.g., massively parallel sequencing), forensic scientists must be aware of and account for potential variability in the cell lines used as controls in their validation studies and day-to-day casework. In this study, multiple lot numbers from four commonly-used control cell line DNAs were sequenced with massively parallel sequencing on the Ion S5. The variability among these different lots was evaluated, and the effect on forensic laboratory work discussed.
