  • Title: A method for the isolation of nuclear DNA from cotton (Gossypium) leaves.
    Author: Dabo SM, Mitchell ED, Melcher U.
    Journal: Anal Biochem; 1993 Apr; 210(1):34-8. PubMed ID: 8098189.
    Abstract:
    Cotton leaves contain high levels of polyphenolic compounds that irreversibly interact with proteins and nucleic acids during DNA isolation. A procedure to isolate nuclear DNA from cotton (Gossypium hirsutum L.) has been developed. The method is based on the rapid initial isolation of nuclei in a glucose medium designed to stabilize nuclear structure and composition while preventing covalent interactions with polyphenolics. The resulting DNA is high in yield and purity and is suitable for Southern-blot hybridization analysis and restriction fragment length polymorphism analysis.
