IntelliGenetics has experience with forensic testing of all types of evidence including, but not limited to:
- BONE & TEETH
- BODY FLUIDS (BLOOD, SALIVA, & SEMEN)
- MIXED & DEGRADED SAMPLES
- TOUCH DNA
IntelliGenetics can test and compare a wide variety of samples to determine if they match and if so, how they match. Perhaps the two samples come from two different unrelated people. Perhaps the DNA from the two samples have identical DNA profiles and therefore, must come from the same person (or an identical twin, see the Educational Forum). Or, maybe the two samples come from different people who are related to one another. IntelliGenetics can determine if the DNA from the two samples are related and if so, how they are related. DNA analysis is performed using an Applied BioSystems Inc. (ABI) capillary electrophoresis platform and ABI PCR Amplification kits (IdentifilerTM) to analyze Short Tandem Repeat (STR) loci. These include the 13 CODIS (COmbined DNA Index System) Core Loci D3S1358, vWA, FGA, D8S1179, D21S11, D18S51, D5S818, D13S317, D7S820, D16S539, CSF1P0, TH01 and TPOX as well as amelogenin for gender determination and STR loci D19S433 and D2S1338. Y-Chromosome analysis is also available for mixed specimens and sexual assault cases for male specific identification. The Y-chromosome is passed from the father to all his sons. Daughters get an X-chromosome from mom and an X-chromosome from dad, whereas sons get an X from mom and a Y from dad. Therefore, all of the males in a family (with the same paternal lineage) will have the same Y-chromosome. Our forensic laboratory can determine if a sample is semen, blood, or saliva. If the sample contains DNA, it can be tested to see whether or not the DNA profile matches a reference sample from a known source.
