To express chicken osteoprotegerin in Pichia pastoris and determine its inhibitive effects on mature osteoclastic bone resorptive function in vitro. The chOPG cDNA encoding for 382 amino acid without signal peptice was subcloned into Pichia pastoris expression vector pPICZα-A. The constructed plasmid was transformed into yeast X-33 by electroporation. The recombinant transformants were selected by Zeocin. Induced by the addition of methanol every 24 hours, the product analyzed by SDS-PAGE was sized about 43kDa and 53kDa at a yield of 200mg per litter of culture. The result of Western blotting indicated that the recombinant protein had specific antigenicity mainly owing to heterogeneous glycosylation.

The deleted mutant PAP gene was also cloned into yeast secreted expression pPIC9K vector to form pPIC9K~3, then the vector was transferred into Pachia pastoris GS115 strain. The specific expression protein was secreted into the medium after inducing with methanol and the protein amount reached about 50-60 U g per millilitre measured by UV-absorbed methods in the supernatant of the medium via high density fermentation. SDS-PAGE results showed that there was one protein band in the gel which molecular weight was about 34Ku . The protein could specific react with France PAP antiserum in Western-blotting.
