A recombinant form of hirudin (HIR), a potent thrombin inhibitor derived from the leech Hirudo medicinalis, was cloned and expressed in the methylotrophic yeast Pichia pastoris. The HIR gene was inserted into the P. pastoris pPic9K expression vector such that the gene's expression is under alcohol oxidase (AOX1) promoter control and the HIR coding sequence(More)
To confirm the treating effectiveness of midkine as an articular protective agent, mouse midkine (mMK) was produced for the pre-clinic long-term studies in mice. The protein was expressed under the control of the AOX1 gene promoter in Pichia pastoris, X-33 strain, and secreted into fermentation broth through high-density fermentation. Approximately 380 mg(More)
S100A6, as a member of S100 protein family, have biological functions in cell proliferation, differentiation, morphology, cytoskeletal organization and apoptosis. In the last three decades, S100A6 has been caught more and more attention. Here, we introduced a simple and efficient method for producing high-purity recombinant human S100A6 from Escherichia(More)
