DNA sample preservation solution is widely used in molecular biology and genetic research to maintain the integrity of DNA samples for extended periods. It is essential in biobanking, where biological samples are stored for future research, diagnostics, or therapeutic purposes. The solution stabilizes DNA by preventing degradation caused by enzymatic activity, oxidation, or microbial contamination. This ensures that the genetic material remains intact and suitable for downstream applications such as PCR, sequencing, or genotyping. In forensic science, it is used to preserve DNA evidence collected from crime scenes, ensuring accurate analysis and reliable results over time. Additionally, it is employed in clinical settings to store patient DNA samples for genetic testing, disease diagnosis, or personalized medicine. The solution is also valuable in field research, where immediate access to laboratory facilities may not be available, allowing scientists to collect and preserve samples in remote locations. Its use significantly enhances the reliability and reproducibility of genetic studies by maintaining sample quality.
