Z-DNA affinity chromatography.

R Fishel, P Anziano, A Rich

    Methods in Enzymology
    |January 1, 1990

    Summary
    This summary is machine-generated.

    Researchers developed a versatile method to immobilize DNA onto chromatography matrices using avidin-biotin technology. This technique enables the creation of specialized columns, like one for Z-DNA, to purify specific DNA-binding proteins.

    Area of Science:

    • Biochemistry
    • Molecular Biology
    • Chromatography

    Background:

    • Purification of specific DNA-binding proteins is crucial for understanding gene regulation.
    • Existing methods for DNA immobilization may lack versatility or efficiency.

    Purpose of the Study:

    • To present a generalized method for linking DNA substrates to chromatography matrices.
    • To demonstrate the application of this method for creating a Z-DNA affinity column.
    • To enable the identification and purification of Z-DNA-binding proteins.

    Main Methods:

    • Utilized avidin-biotin technology for end-specific linkage of DNA to a chromatography matrix.
    • Constructed a left-handed Z-DNA affinity column using the developed method.

    Main Results:
