Production of GAD65 in methylotrophic yeast

摘要

Methylotrophic yeast are used for high-level expression of GAD65 that makes the production of GAD65 feasible on an industrial scale. A methanol-inducible promoter from, for example, an alcohol oxidase gene, such as Pichia pastoris AOX1, can be used to regulate GAD65 expression. The recombinant GAD65 has high specific activity and retains antigenic characteristics of the native molecule that are essential to immunological assays and therapeutic protocols.
