Figure 4.
OPN distribution in fractions obtained with ceramic hydroxyapatite (CHT) resin (a) with no salt; (b) with 250 mM NaCl. Step elutions were performed with sodium phosphate (NaP) buffer, pH 6.8. Data (% OPN) were generated by ImageJ analysis of anti-FLAG western blots and normalized by the amount in the lysate. Error bars indicate standard deviation of triplicate ImageJ measurements.
