DNA identification is about to become a much simpler task, thanks to the expertise of a Welsh business.
With more crime cases being determined by a DNA profile, Usk-based engineering company GX Design is pioneering the next generation of testing equipment.
While DNA provides a fail-safe match, the process of actually isolating the delicate genetic material is both highly complicated and laborious.
To extract the DNA from a sample it must be put through a series of heating and cooling cycles which have to be absolutely precise.
The DNA is then duplicated to allow multiple testing.
Working in partnership with Californian company Apollo Instrumentation, GX Design has just developed the most advanced DNA extraction and duplicating equipment produced to date.
It says it has brought the technology forward by 15 years.
Its Thermal Cycler uses a full computerised heating and monitoring system, enabling technicians to work both more quickly and more accurately. GX Design director Frank Marsh said, ``We are quite well known in the States, thanks to our work for the well-known health-care company Bayer over the past six years.
``It may seem a little strange for a rural-based business like ours to be working with some big names in America, but we have been quietly building up our reputation over the past seven years. …
