A small amplicon (~60-125 bp) DNA typing system for challenging forensic samples that is compatible with currently used Capillary Electrophoresis (CE) instrument platforms.
- Obtain DNA profiles from Rootless Hairs
- Achieve informative results with degraded/low level samples
- High sensitivity –obtaining profiles with as little as 15 – 30 picograms total DNA*
- Significantly more discriminating and less labor-intensive than mitochondrial DNA sequencing
- Compatible with DNA•VIEW DNA Analysis Software
With the ability to obtain informative results from heavily degraded samples with as little as 15 – 30 picograms total DNA*, InnoTyper 21 provides a discriminating alternative to mitochondrial DNA (mtDNA) sequencing, which is currently the genotyping standard for degraded samples such as old human remains and hair shafts. InnoTyper 21 is significantly more discriminating and less labor-intensive than mtDNA sequencing, and does not require a specialized workflow.
Studies have also demonstrated the utility of InnoTyper 21 for highly compromised human remains, i.e. bone fragments, that have failed to yield informative results using other methods, as shown in Figure 4. (For complete study details, see here.)
