“…The K value decreased on increasing the [K + ] from 50 to 130 mM. Earlier studies on the induction of self-structure by small molecules like methylene blue, chelerythrine, proflavine, azure A and azure B have shown that the K value increases with increase in salt concentration [30,32,34,35]. However, in the case of coralyne here the K values decreased from {(3.12 ± 0.12)Á10 6 to (2.46 ± 0.11)Á10 6 to (1.91 ± 0.09)}Á10 6 M À1 on increasing the [K + ] from {(50 ± 0.01) to (75 ± 0.01) to (100 ± 0.01)} mM.…”
