Heparin-Sepharose column fractions. Peptides in Table 1 were bound to a heparin-Sepharose column and eluted with NaCl at concentrations of 0.01, 0.15, 0.5, 1.0, and 2.0 M. The optical densities of the fractions of most peptides were determined in the at a wavelength of 280 nm. Representative examples of the optical densities of fractions from three peptides in Table 1 are shown in panels A-C in which the NaCl concentration at which the peak fraction eluted is written above the peak.
