Y-STR Casework |
The Bode Technology Group can supplement conventional STR analysis with Y-STR analysis on forensic casework samples. Under certain circumstances, conventional STR analysis may fail to clearly distinguish the male contributor DNA in a mixed sexual assault sample. Y-STR analysis can provide the clarity necessary to render a conclusion regarding the inclusion or exclusion of a specific individual. Forensic mixtures may contain cell types that cannot be separated using differential extraction techniques (e.g., dried saliva stain on a victim's leg). If the male DNA isolated from the sample is a low-level minor component, Y-STR analysis can provide useful information regarding the identity of potential contributors. The Bode Technology Group has developed a unique Y-marker screen that identifies male component DNA prior to STR analysis. This Y-marker system is more sensitive than STR methods to ensure that low levels of male component DNA are identified. Even if subsequent STR analysis fails to yield a male profile, the presence of Y-marker DNA may be useful for investigative purposes. Privacy
