Figure 2: Corrected peak width as function of pH of SP (circles and solid line) and Tyr-Gly (squares and dash-dotted line) fractionated by the Fractogel HW-40 described under “Chromatographic procedures”. Symbols represent experimental points, lines exponential growth and first degree polynomial interpolation for SP and Tyr-Gly, respectively. Chromatographic conditions as described in the text.
