FOXL2 is a member of the large family of winged helix/forkhead transcription factors involved in ovarian development and function. Herein we cloned the FOXL2 from the giant panda genome. The FOXL2 was sequenced, analyzed and expressed in E .coli BL21 and in HEK293 cells. The ORF of FOXL2 was inserted into prokaryotic expression vector pET-32a (+) to constructed recombinant expression plasmid pET-32a(+)-FOXL2 and expressed in E.coli BL21 by IPTG induction. A recombinant eukaryotic expression vector FOXL2-pcDNA3.1/V5-His C was constructed, the recombinant plasmid was transfected into HEK293 cells with Lipofectamine 2000 and the fusion protein was identified by Western blot analysis. SDS-PAGE and Western blot analysis showed that the recombinant FOXL2 was highly expressed at 4 hours after IPTG induction and the expressed product of FOXL2 was about 58.9 kDa which was recognized by His monoclonal antibody. The results could be useful for further study of the bioactivity and application of FOXL2.
