DNA extraction of peripheral leukocytes is the most broadly used technique to obtain DNA. However, cell collection from an oral swab, frequently used in forensics, is useful to obtain DNA samples, mainly in newborns, children and patients who live far from the collection sites, where blood sample collection and sending is not feasible. Our objective was to standardize DNA extraction from an oral swab, using the NaCl method, comparing it with a commercial kit. To test DNA quality, we amplified […]
