Efficient Production of Recombinant Human Pleiotrophin in Yeast, Pichia pastoris(Microbiology & Fermentation Technology)

概要

論文の詳細を見る
Approximately 260 mg/l of authentic recombinant human pleiotrophin (rhPTN) was expressed into the medium of high-cell density fermentation using a Pichia pastoris protein expression system. The preprosequence of yeast α-mating factor was used successfully. The recombinant hPTN was efficiently recovered from the medium by expanded bed adsorption, and purified using successive column chromatography steps. In the purified rhPTN preparation, modified rhPTN were scarcely detected. Circular dichroism measurement of the purified PTN showed the presence of the characteristic β-structures in the protein.
