To obtain the recombinant core domain of porcine zone pellucida 3β （cZP3β） for the further research on its functions Methods The nucleotide sequence region from 44 to 306 codons of pZP3β entire eDNA was obtained ...To obtain the recombinant core domain of porcine zone pellucida 3β （cZP3β） for the further research on its functions Methods The nucleotide sequence region from 44 to 306 codons of pZP3β entire eDNA was obtained by PCR and then was cloned into pET-3c vector. After being identified, recon was transformed into E.coli BL21 （DE3） pLysS and then induced by IPTG. Results The recombinant cZP3β was expressed in E. coli up to 15% of total cellular proteins, and was made sure by Western blot analysis. Conclusion The research on expression of core domain of pZP3β could benefit to further investigation of its immunogenicity and the development of antigen preparation.展开更多
