Reverse-phase HPLC analysis of hG-CSF. Sulphoxides and deamidates in hG-CSF were analyzed by Reverse-phase HPLC. 200 μg mL^-1 of either sample or standard was loaded for analysis. (A): homogeneous hG-CSF, peak 1-main peak. (B): reference standard, peak 1-main peak. Absorbance is in milliabsorbance units (mAU).
