A comparative study on UV spectrophotometric quantification of DNA extracted from human saliva

AbstractThe objective of the present study was to extract and quantify DNA from 48 fresh saliva samples and 48 dried saliva stains that had been stored for 21days. Quantization was performed using a 260nm UV spectrophotometer. Concentration of DNA extracted from fresh and dry samples ranged from 15–795μg/ml. The results indicate a wide range of DNA yields from saliva samples and provide information for the forensic scientific community to interpret or correlate DNA yields from saliva stains
