Production of a high-density MicAsa RNA array. (A) Preparation of a high-density DNA template array of MicA and MicAsa. (i) Schematic layout of a single 6 × 6 grid with alternating rows of MicA and MicAsa templates. (ii) A single 6 × 6 grid of a DNA template array of Alexa647-labelled MicA and MicAsa. Individual spots were separated by 750 μm. (iii) The entire DNA template array of 21 repeating 6 × 6 grids as shown in (ii). (B) Production of a high-density MicAsa RNA array from the DNA template array described in (A). (i) Schematic of the expected layout of a single grid of the MicAsa RNA array. (ii) A single grid of the Cy3-labelled MicAsa RNA array. (iii) The entire MicAsa RNA array of 21 repeating grids as shown in (ii). The RNA array images have been mirror imaged so that the spot positions correspond to those shown in the schematics of the DNA template array.
