  • Ion-exchange chromatography

    Separation of ionic compounds (which include nucleic acids and proteins) in a chromatographic column containing a polymeric resin (i.e., the stationary phase) having fixed charge groups. The process works in that the charges of the column (stationary phase) interact with the opposite charges of the material dissolved in the solution that is flowing through the…

  • Invasin

    A transmembrane (i.e., through the membrane of the cell) protein that enables bacterial cells to invade normal (body) cells.  

  • Introgression

    The incorporation of transgenes (genes from transgenic organisms) into a wild type’s genome.  

  • International society for the advancement of biotechnology (ISAB)

    A nonprofit organization of individuals that was started in 1994 “to advance and promote the general welfare of the science and commercialization of genetic engineering and industrial biotechnology.”  

  • International plant protection convention (IPPC)

    One of the three international SPS standard-setting organizations that is recognized by the World Trade Organization (WTO), the IPPC is the worldwide authority for development ofplant health standards, guidelines, and recommendations (e.g., to prevent transfer of a plant disease from one country to another). The treaty establishing the IPPC was signed in 1952. IPPC standards…

  • International office of epizootics (OIE)

    One of the three international SPS standard-setting organizations that is recognized by the World Trade Organization (WTO), the OIE is an international veterinary organization headquartered in Paris. The OIE was established in 1924, originally as part of the League of Nations, and is the worldwide authority for development of animal health and zoonoses standards, guidelines,…

  • International food biotechnology council (IFBC)

    An organization that was established in 1988 by the Industrial Biotechnology Association (IBA) and the International Life Sciences Institute (ILSI), in order to “produce a (recommended) set of guidelines that could be used to assess the safety of genetically altered foods.”  

  • Intermediary metabolism

    The chemical reactions that take place in the cell that transform the complex molecules derived from food into the small molecules needed for the growth and maintenance of the cell. The series of intermediate compounds formed during digestion before the final excretion or oxidation products are formed or eliminated from the body.  

  • Interleukin-9 (IL-9)

    A cytokine (glycoprotein) that is released at sites in the body where inflammation has occurred.  

  • Interleukin-8 (IL-8)

    A basic polypeptide (glycoprotein) with heparin-binding activity. Endogenous endothelial IL-8 appears to regulate transvenular traffic during acute inflammatory responses.
