    摘要: Described are methods for separating hemagglutinin (HA) antigens, comprising the steps of applying a reduced and derivatized antigen preparation comprising solubilized HA antigens and a detergent in a pH controlled solution, on a Reversed-Phase High-Performance Liquid Chromatography (RP-HPLC) column; and eluting the HA antigens from the column with an ion pairing agent in an organic mobile phase. The invention further relates to quantifying methods using the methods for separating the antigens with the further step of measuring the peak area of the eluted antigen in a chromatogram resulting from the elution step.
