QIAO XIANFENG~1, LIU XIMEI~1, AN LIGUO~2, et al. Cloning of the Swine Pepsinogen A Gene and Expression in Pichia pastoris. [J]. 2006, (4): 508-512.DOI:
The total RNA was extracted from swine gastric mucosa
which acted as the template to get a 1.24 kb segment of swine pepsinogen A gene cDNA by RT-PCR.The cloned cDNA was ligated into EcoRⅠ and Not I sites of the vector pPIC3.5K downstream with the AOX1 alcohol oxidase promoter and transformed into Pichia pastoris GS115.The transformants grew in shaking flask and were induced by methanol
then analyzed by SDS-PAGE
the results showed swine pepsinogen(EC 3.4.23.1) A gene was expressed successfully in Pichia pastoris GS115.
