Where advanced technology meets forensic science
4N6FLOQSwabs are specifically designed for DNA collection and use in forensic applications, such as databasing and sexual assault, as well as paternity testing and evidence collection (including sweat, semen, blood stains, skin, and any traces found at crime scenes). The patented FLOQSwabs are comprised of a solid molded plastic applicator shaft with a tip that can vary in size and shape and is coated with short nylon fibers that are arranged in perpendicular fashion. FLOQSwabs have no internal absorbent core to entrap the specimen like traditional fiber swabs, so the entire sample stays close to the surface for fast and complete elution.
Benefits
- Support DNA yield with improved sample release
- Boost efficiency and accuracy with increased DNA yield
- Reduce sample manipulations with convenient breakpoints
- Streamline laboratory processes
Applications
Crime scenes
At crime scenes, it is essential that the swab maximizes DNA collection while preserving nucleic acid integrity. 4N6FLOQSwabs are specifically designed for sample collection of sweat, semen, blood stains, skin, and trace evidence. They are optimized for challenging samples, with a rapid absorption capability and superior sample release that are especially valuable when working with limited or trace amounts of DNA.
Disaster victim recovery (DVI)
Human remains
In the aftermath of a disaster, identifying victims becomes critical for recovery efforts. DNA collection plays a crucial role in this process, enabling the identification of victims by comparing DNA samples with those of their relatives. Swabs have emerged as a reliable tool for collecting DNA samples from victims, offering several advantages over other methods. Key features to consider when using swabs for DVI:
- Ease of use
- Maximizing DNA collection
- Preservation of DNA
Reference samples
The establishment and maintenance of a comprehensive DNA reference sample database are essential for effective crime scene investigation and identification of individuals. 4N6FLOQSwabs are widely used for DNA collection in forensic database workflows, offering numerous advantages, including
- Ease of collection
- Preservation of DNA integrity
- Efficient analysis
