Production of a low-density multi-RNA array. (A) Generation of a Cy3-labelled MicAsa, hapRsa and MGsa RNA array (i) Schematic layout of a DNA template array of MicA, MicAsa, hapR, hapRsa, MG and MGsa. (ii) Cy3-labelled RNA array generated from the DNA template array following in vitro transcription.(B) Probing a low-density multi-RNA array with malachite green. (i) Schematic representation of the middle row of a non-labelled RNA array generated using the DNA template array in A(i). (ii) As in B(i) following probing with malachite green. (iii) A non-labelled MicAsa, hapRsa and MGsa RNA array (i) (generated as in (A) but without labelling) probed with malachite green. 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.
