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.

为了在毕赤酵母中分泌表达鸡骨保护素（osteoprotegerin，OPG），采用DNA重组技术将chOPG成熟肽cDNA片段插入毕赤酵母表达载体pPICZα-A中，以电穿孔法转化酵母X-33，用Zeocin 平板筛选重组子，经甲醇诱导表达后， SDS-PAGE 和免疫印迹分析表达产物，由于糖基化不同，表达产物有两种，其相对分子量分别为43kDa和53kDa，表达量约为200mg/L，经Western印迹验证，有较好的抗原性。
