花鳗鲡重组促黄体生成素在毕赤酵母中的表达
Expression of A Recombinant Luteinizing Hormone of Marble Eels,Anguilla marmorata Using Methylotropic Yeast, Pichia pastoris
摘要
Abstract
The GTHα、LHβ gene fragments were amplified by PCR, which the template was pituitary cDNA of marble eels. In the way of bridging, the two fragments were connected to a single gene LHβα, a linker inserted between them. The LHβα gene fragment was subcloned to pPICZαA with double enzyme digestion and connection, constructing eukaryotic co-expression plasmid pPICZαA-LHβα. The recombi-nant plasmid was transfected into a native yeast strain X-33 by electrotransformation. The high-copy clones were selected by the YPDS plates containing different concentrations of Zeocin. The positive clones were induced by 0.7% methanol and expression products were tested by SDS-PAGE and western blot, and its molecular weight was determined as about 45 000.关键词
