Application of species-specific polymerase chain reaction in the forensic identification of tiger species

Globally, tigers are considered to be endangered, and are listed on Appendix I of CITES. A simple test, using a species-specific primer pair, was developed to identify tiger meat, faeces and dried skin, and provide forensic evidence of illegal wildlife trade. The specific fragment of mitochondrial cytochrome b gene was also successfully amplified from raw DNA products extracted from single tiger hairs. This PCR-based approach opens a new avenue to forensic identification of less-than-optimal samples.
