目的 :探索毕赤酵母表达的人瘦素的非亲和层析纯化方法。方法 :采用强阴离子交换柱 (SepharoseQfastflow)和疏水层析柱 (PhenylSepharose 6fastflow)在 pH 7.5的条件下进行纯化。结果 :经Q柱一步纯化后
产物纯度由 4 2 .3%到达89 .6 %
随后通过疏水层析纯化后
产物纯度达到 96 .2 %。经SDS -PAGE证实为单一蛋白条带。结论 :通过上述手段已成功分离纯化得到纯度较高的由毕赤酵母表达的重组人瘦素。
Objective:To explore the purification method of non- affinity chromatography for leptin expressed in Pichia Pastoris.Methods:Ion exchange chromatography (Sepharose Q fast flow) and hydrophobic interaction chromatography (Phenyl Sepharose 6 fast flow ) were used to purify human leptin in pH 7.5. Results: After purification by Q column
the purity of leptin increased from 42.3% to 89.6%.Subsequently
after hydrophobic interaction chromatography
its purity reached 96.2%. In SDS-PAGE
leptin was shown as one specific band.Conclusion:The human recombinant leptin expressed by Pichia Pastoris yeast can be successfully purified by ion exchange chromatography plus hydrophobic interaction chromatography.
