Forensic DNA samples can be affected by coextracted materials (PCR inhibitors) present at a crime scene. Using Multiplex PCR amplification and real time PCR with high resolution melt capability, we are examining a variety of PCR inhibitors with respect to DNA sequence and polymerase binding. We model their effects and work on better ways to reduce inhibition to permit forensic scientists to improve the quality of their data.
