Abstract: Quantifying DNA-protein interaction using DNA microarrays are gaining increasing attention due to their ability to profile specificity of interactions in a high-throughput manner. This paper describes a new approach that used the ability of ssDNA-dsDNA probe to complex with DNA binding proteins in the solution phase and then spatially immobilized onto microarray through specific DNA hybridization. In one case, the Spatially Addressable DNA Array (SADA) approach demonstrated that enzymatic cleavage in solution is more efficient than if conducted heterogeneously. In addition, binding of RNA polymerase with promoter DNA could be detected with this strategy.
