Measurements of the relative quantum yield of fluorescence of proflavine bound to DNA as a function of the number of bound dyes per nucleotide and the ionic strength allow the determination of the binding constants and respective number of the two types of sites previously postulated. It is demonstr
## Abstract Proflavine binding may be used as a probe of the environment and interactions of DNA. In this paper we report the effects of the divalent cations Mg^++^ and putrescine and the trivalent cation spermidine on the proflavineβNa DNA binding equilibrium. Difference spectroscopy at 430 nm was
## Abstract We have measured the binding equilibria of proflavin to T2L bacteriophage, in both βslowβ and βfastβ sedimenting forms, and to free T2L DNA. Measurements were carried out by difference spectroscopy at 430 nm at temperatures from 13 to 43Β°C and at pH 5.6 and 7.6. We found no significant
