To study the expression, purification and bioactivity of human augmenter of liver regeneration in Pichia Pastoris, the expression plasmid pPICZαA- ALR was constructed and transformed into P. Pastoris by the method of electroporation transformation. Induced with 0.5% methanol, the 30 kD protein in the culture supernatant of recombinant P. Pastoris was confirmed to be rhALR by SDS-PAGE and Western blot. Quantitative analysis showed that the target protein was in a level of 66% of the total protein of the culture supernatant, with a yield of 40mg/L.we had performed DEAE anion exchange chromatography two times with excessive and regular adsorption quantity consecutively, and then the rhALR above 95% purity and 52% protein recovery could be obtained by G75 molecular sieve chromatography at last step. The bioactivity assay of the purified product showed that rhALR could stimulate the proliferation of HepG2, SMMC-7721 and NIH-3T3 in vitro.

为在毕赤酵母中分泌表达人肝再生增强因子，以色谱法分离纯化后进行体外活性研究，构建表达载体pPICZαA- ALR，经电穿孔转入毕赤酵母中，用0.5％甲醇诱导表达；重组酵母培养上清经SDS-PAGE电泳和western blot鉴定后表明， rhALR以分子量为30kD的二聚体为主；定量分析结果表明，重组酵母培养上清中rhALR约占总蛋白的66％，表达量约为40mg/L；经DEAE柱和G75柱纯化后，获得的rhALR纯度大于95％，得率为52％；体外生物学活性实验表明，rhALR能明显促进HepG2、SMMC-7721和NIH-3T3细胞的增殖。
