The Casework Direct System allows you to rapidly process swabs from casework samples or cuttings of sexual assault swabs and stained fabric prior to quantification of human DNA using either Plexor(R) HY or the PowerQuant(R) Systems, and amplification of normalized template using PowerPlex(R) Systems for STR analyses. For casework samples, no further purification of the Casework Direct lysate is required prior to STR amplification unless data from the quantification step suggests that PCR inhibitors may be present.
