Z-DNA affinity chromatography.
In this chapter we have detailed a method that can be generalized to link virtually any DNA substrate to a chromatography matrix at its ends via an avidin-biotin linkage. We have used this technique to construct a left-handed Z-DNA column for the purpose of identification and purification of Z-DNA-binding proteins. This technique for the linkage of DNA to a column matrix by avidin-biotin technology can be modified, however, to produce linked multimeric sequences specific for regulatory or other DNA-binding proteins.
