VILNIUS, Lithuania—To overcome challenges presented by existing DNA testing methods using the “curtain method,” which captures images of the interactions between proteins and DNA at a single molecular level, scientists from the Vilnius University Life Sciences Centre (VU LSC) and the Center for Physical Sciences and Technology (CPST) have jointly-developed an alternative approach called the Fixed DNA Molecule Array method—a solution they say makes DNA testing more simple and more cost-effective.
The solution developed in Vilnius, the capital of Lithuania, reduces costs and time due to its use of a blueprint that can be used repeatedly as opposed to just once. It is estimated by VU LSC and the CPST that this approach can reduce the cost of one DNA testing experiment by 90 percent.
One of the leaders of the Fixed DNA Molecule Arrays project, Dr. Mindaugas Zaremba, believes that the alternative to the DNA curtain method will not be the last ‘Vilnius-made’ solution to contribute to the advancement of international science. The project brought together biochemists exploring DNA-interacting proteins from VU LSC, and CPST’s physicists who used Lithuanian-developed laser technologies to explore the molecules.
“This latest achievement shows the strong spirit of collaboration between the sciences in Vilnius," he commented. "Without biochemistry, we would not have been able to obtain the correct proteins for the research. Without the lasers, we would not have been able to observe these molecules and their behaviour. If we continue to work closely together and work on the development of our talented scientific community, I do not see why Lithuania, especially Vilnius, cannot become a hub of European scientific breakthroughs and international export of the future."
