The asymmetric unit is rA2, however the input RNA polymer is rA7, and this forms a continual parallel poly(rA) double helix structure. This structure is referred to as a "staggered zipper" since the rA7 strands overlap in a many different registers relative to their opposite, paired strands, to form the helix.

One uL of this was mixed with 1 uL of the following reservoir solution: (0.24 M ammonium sulfate and 0.06 M citric acid pH 3.5) to generate a hanging drop over 1 mL of this reservoir solution.
