This research is taking sea perch as the material, and cloning the Syntaxin 1B gene. After extracting RNA from sea perch tissue, we gained the first chain of cDNA by RT-PCR. Then designing a pair of primers according to the sequence of Syntaxin 1B from other organism. Based on the first chain of cDNA cloned from sea perch, the partial sequence of Syntaxin 1B gene is been cloned by using TD-PCR and we received the 751bp fragment at last.
