Abstract

Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis and lab-on-a-chip system were used to identify grouper and snapper species in Taiwan Strait. A fragment of 464 bp length of mitochondrial cytochrome b gene was amplified by PCR and the products were digested with restriction enzymes Dde I , Hae III and NLa III, individually. The fragments generated after digestion were further resolved on the DNA Chip. Eight grouper species and five snapper species were successfully identified. The results demonstrated that PCR-RFLP analysis and lab-on-a-chip system provide a fast, easy, automated, and reliable analysis approach. This approach is potential for the purpose of fish adulteration control.
