| Abstract: | To detect the mammalian target of rapamycin (mTOR) expressed in Cashmere goat fetal fibroblasts (GFb), mTOR gene was cloned from Inner Mongolia Cashmere goat (Capra hircus) and expressed in Escherichia coli followed by immunizing mice with the purified recombinant protein as an immunogen to produce the anti-goat mTOR recombinant polyclonal antibody. Antiserum was collected from the immunized mice after the fifth immunization and its titer was determined with enzyme-linked immunosorbent assay (ELISA). The results showed that the recombinant polyclonal antibody had a titer 1:200 000 and could react with the mTOR expressed in GFb cells with a specific and sensitive affinity. Western blot showed that mTOR expression and phospho-mTOR (Ser 2448) activity were inhibited when GFb cells were treated with CCI-779, an mTOR specific inhibitor. |
