Tissue Homogenizers – Sample preparation for Forensic - Manufacturing, Other

Extremely hard samples such as bone, teeth, and hair are common in forensic laboratories. Popular downstream applications include DNA extraction from bone or teeth and drug extraction from hair.

Biological evidence is available in small quantities, and it is a challenge to extract high-quality DNA from scarce, organic material.

In cases of alcohol abuse, physicians closely monitor abstinence while patients undergo alcohol withdrawal treatments. Precellys tissue homogenizer is used to extract ethylglucuronide (EtG), a highly specific alcohol biomarker, from hair samples using liquid chromatography tandem mass spectrometry. Precellys can be used to dry-grind hard samples such as bone or hair, which typically represents a challenge for many forensics laboratories, and offers an alternative solution to improving DNA and drug extraction yields from scarce biological material.
