    Abstract:
    The verification of authenticity of meat products is relevant for economical, religious or public health concerning reasons. A molecular approach using terminal restriction fragment length polymorphism (T-RFLP) was developed to distinguish 12 common economically important meat species. The partial 12S rRNA gene was amplified with double-fluorescently labeled primers. The amplified fragments were digested with two endonucleases and only the terminal restriction fragment containing labeled primer was detected on capillary electrophoresis system ABI3100. AluI and Tru9I generated differently-sized terminal fragments in different species. Pig and buffalo can be separated by 3'-terminal fragment of AluI digestion. Horse, turkey, goat, sheep, deer, and cattle can be further separated by 5'-terminal fragment of Tru9I digestion. Dog and chicken, sturgeon and salmon can finally be separated by 5'-terminal fragment of AluI digestion and 3'-terminal fragment of Tru9I digestion. Our results demonstrated the potential feasibility and applicability of T-RFLP method for rapid and accurate identification of animal species.
