Effect of Storage Time on DNA Content and Purity in Lip Print

Forensic experts in uncovering the truth of a case must go through identification, documentation, and collection evidence. Sometimes at crime scene, lip prints are found on surface an object such as mouth plastic bottle. Lip print research bottle mouths was carried out for 1, 3 7 days. There 21 samples with details controls, 6 first day, 3rd 7th day. DNA extraction using DNAzol, quantification UV spectrophotometer, amplification STR primers, namely TPOX TH01 loci. For visualization acrylamide gel. The average results levels 3, days were 369.82 g/ml, 550.72 318.02 g/ml. yield purity 1.79; 1.78 1.79. From quantification, lowest highest taken 7. Of controls amplified loci, clearly visible gel band.
