The killer outfit and timing: impact of the fabric and time in body fluid identification and DNA profiling

The present work aimed to study the detection, through lateral flow immunochromatographic (LFI) tests, of saliva samples over time in three different types of fabrics, as well as, the possibility of DNA isolation and characterization from the sample tubes and the cassettes. Fifty microliters of saliva (three samples/time) were deposited in denim, cotton, and polyester. Saliva was identified by SERATEC Amylase Test and the Crime Scene version SALIVA CS, being able to detect it up to six months of deposition, although with different band intensities.
