Figure 6.

Dependence of effective electrophoretic mobility of (a) bilirubin-10-sulfonate (ranarubin) and (b) UCB. Background electrolytes 1–3, 6, 9–13 were used for the bilirubin-10-sulfonate studies; background electrolytes 3–5, 7, 8 for the UCB studies. Depicted points are the mean ± SD values of three experimental values. The position of the inflection points was determined using the numerical interpolation procedure using the standard Boltzmann sigmoidal function defined in the Origin software (Origin (Pro), Version 2016, OriginLab Corporation, Northampton, MA, USA Corporation, MA USA).
