Macromolecular interactions are central to the regulation and execution of many key biological processes, and therefore, they are attractive targets for drug discovery. Previously, we identified an RNA aptamer for the heat shock factor (HSF1), which is capable of interfering with the binding of HSF1 to its cognate DNA elements. Here we report the significant enhancement of avidity through dimerization of this aptamer. In particular, we describe the effect of 2 factors in designing a multivalent aptamer: the distance between active subunits and the flexibility of the linkage.
