  • Patent number: 9120724
    Abstract: A method for producing an absolute alcohol containing not more than 0.4 mg/L of acetal by subjecting a raw material alcohol to a zeolite membrane treatment, the raw material alcohol being obtained by distilling a crude alcohol, and having an alcohol concentration of not less than 95 v/v%, and the raw material alcohol containing not more than 5 mg/L of acetaldehyde and not more than 60 mg/L of a total amount of organic impurities. An absolute alcohol can be produced, which absolute alcohol is highly safe to the human body and has a quality that no off-odor is felt by human senses. In addition, the contents of diacetyl and crotonaldehyde in the raw material alcohol may be set at levels not more than particular values, respectively.

  • Publication number: 20080044903
    Abstract: Improved methods for transferring a gene into target cells by using a retrovirus, wherein the gene transfer efficiency is improved and the target cells are efficiently transformed by binding the retrovirus to a functional substance which is immobilized on as carrier and having an activity of binding to retroviruses followed by washing; using an antibody capable of specifically recognizing cells, laminin or mannose-rich type sugar chain as a substance having an activity of binding to the target cells; pre-treating the target cells so as to inactivate transferring receptor, or introducing a new functional group into the functional substance.
