3.In 1936 Edwin Jelley sent a ‘Letter to the Editor’ of Nature, (138 1009 -1010), regarding the unusual behaviour of some cyanine dyes.

4.When dissolved in 5 M NaCl these dyes produce a third absorbance peak at a longer wave-length (650nm) whereas in deionised water only a double peak occurs at ~540 nm and ~570 nm.

5.The 650 nm peak in concentration dye solution induces aggregation of the dye molecules and has been described as a ‘J-aggregate’ named after Jelley.

6.Individual dye molecules may form a stacking format to produce a supra-

molecular complex as seen in peak 3, (Image on front cover of the Manual)

7.Further studies in the 1960s notably by Kay et.al. (J. Physical Chem. 68 1896 – 1906) found many biological polymers including proteins, DNA, polar lipids and glycosaminoglycans could induce the third peak when using high dye concentrations.

8.The dye was renamed ‘Stains-all’ by Dhlberg, Dingman and Peacock in1969

( J. Mol. Biol. 41, 139).
