Description
The Biological Trace Developer is a rapid, easy-to-use reagent designed for the visualization of biological traces while preserving DNA integrity for subsequent extraction and analysis. It allows forensic professionals to accurately detect single-source DNA traces, avoiding contamination from mixed DNA. The developer works naturally without the need for darkrooms or special imaging equipment, providing visible results within minutes depending on ambient temperature. The product is suitable for a variety of surfaces, including paper, light-colored wood, plastics, marble, fabrics, ceramics, and painted walls, and is also partially effective on non-porous surfaces like metals and coated glass.
