    摘要: The present invention aims to provide a method which, even when a protein complex is formed, can purify a protein derived from such a membrane protein complex by eluting the membrane protein complex maintaining its complex form. The present invention relates to a method for purifying a protein derived from a membrane protein complex, which includes: a protein binding step of binding to an antibody a membrane protein complex eluted from a membrane using a synthetic polymer; a protein eluting step of eluting the membrane protein complex bound to the antibody in the protein binding step at a pH of 6.0 or higher; and a synthetic polymer removing step of subjecting the membrane protein complex eluted in the protein eluting step to solvent extraction at a pH of 7.0 or lower to remove the synthetic polymer.

    摘要: The present invention provides a method for producing a polyisoprenoid with which it is possible to enhance the rubber synthesis activity of rubber particles to increase natural rubber production. The present invention relates to a method for producing a polyisoprenoid in vitro, which involves the use of a gene coding for a cis-prenyltransferase (CPT) family protein and a gene coding for a Nogo-B receptor (NgBR) family protein, and further involves the use of rubber particles bound to proteins encoded by these genes; or a method for producing a polyisoprenoid, which includes introducing into a plant a vector in which a promoter having a promoter activity that drives laticifer-specific gene expression is linked to a gene coding for a CPT family protein and a gene coding for a NgBR family protein, to express proteins encoded by the genes specifically in laticifers.
