FORENSIC SCIENCES Development of a Human DNA Quantitation System

The AluQuant™ Human DNA Quantitation System has been developed for human-specific quantitation of forensic samples. This system uses probes specific to repetitive genetic elements allowing quantitation without target amplification. Target immobilization is unnecessary with employment of solution hybridization. The AluQuant™ Human DNA Quantitation System uses a series of enzymatic reactions to produce a luminescent signal proportional to the quantity of human DNA present. This report demonstrates a range of quantitation from 0.1-50 ng of human DNA. Signal from non-human DNAs tested was insignificant and addition of non-human DNAs into a human sample did not alter quantitation. Lastly, the system was unaffected by degradation of sample through sonication. The AluQuant™ Human DNA Quantitation System is a simple and sensitive method for quantitating the concentration of human DNA in forensic samples
