For the last few years, law enforcement agencies have seen an uptick in property crime evidence submissions, resulting in the need to use significant laboratory resources to test evidence for “touch DNA”—microscopic skin cells containing DNA that naturally rub off when an object, like a car steering wheel, is touched. When DNA is found at a property crime scene, laboratories are often able to match it to a known offender’s sample in CODIS, the national DNA database.
Integration of the Casework Direct System into a laboratory’s workflow provides a rapid and cost effective means to generate, with minimal hands-on time, high quality STR profiles from precious, low abundance samples. When used with the PowerQuant® System, valuable workflow information such as the presence/absence of male DNA degradation or potential PCR inhibition is provided. STR results from several mock casework samples are provided below.
