Ionic strength dependence of SSB
·ssDNA complex formation. Ionic strength dependence of ssDNA binding by SSBBA was measured at NaCl concentration as indicated. (a) Binding isotherms for SSBBA binding to ssDNA at six NaCl concentrations: 0, 25, 50, 100, 150, and 200 mM. (b) Thermodynamic linkage plot for SSBBA binding to ssDNA as a function of NaCl concentration. The net average number of ions released upon complex formation was derived from the slope of the plot.
