Battelle ExactID Version 2.0

Battelle has launched ExactID version 2.0, which allows forensic analysts using Battelle's ExactID next-generation sequencing system to pull more information out of challenging DNA samples. This version adds new mitochondrial DNA analysis options that provide greater utility for forensic investigators dealing with degraded DNA samples or very limited DNA samples, such as a single hair follicle. ExactID 2.0 also incorporates MicroHap marker analysis that provides more accurate results than is possible with SNP markers in mixed DNA samples. The new version also includes an updated user interface and display.
