Abstract: The DNA copy of samples was detected by applying a real-time quantitative PCR assay with TaqMan Probe and SYBR Green. DNA was abstracted from variety of biological samples common in forensic science. Experiment results show that the real time quantitative PCR has great forensic application potential in the DNA copy quantification and evaluation of inhibiting factors of abstracted DNA.

Key words: fluorescent quantitative PCR, quantification, forensic biological evidence
