DNA profiling was performed on bloodstains and saliva on various supports after treatment with commonly used reagents for developing latent fingerprints.
Abstract
Latent fingerprint samples and bloodstains of three individuals were collected on the surface of razor blades and plastic foils for cyanoacrylate fuming, on glass slides for treatment with amorphous carbon, on the sticky surface of an adhesive tape for gentian violent treatment, and on groundwood- free white paper for ninhydrin treatment. Saliva samples of two individuals were collected on the back of postage stamps for ninhydrin treatment. The study explored the possibility of typing biological stains such as blood and saliva on various surfaces, after development of fingerprints with commonly used methods. Results showed no effect of investigated dactyloscopic methods on DNA typing compared with untreated samples. Specifically, used chemicals had no influence on DNA extraction, DNA quality, and DNA typing of samples subjected to dry storage at room temperature. 22 references, 1 table, and 5 figures
