Hepatitis B surface antibody imprinted poly(hydroxyethyl methacrylate-N-methacryloyl-L-tyrosine methyl ester) particles were prepared for the purification of hepatitis B surface antibody from human plasma. N-methacryloyl-L-tyrosine methyl ester was chosen as a complexing agent for hepatitis B surface antibodies. Hepatitis B surface antibody imprinted poly(hydroxyethyl methacrylate-N-methacryloyl-L-tyrosine methyl ester) particles were characterized by surface area measurements, swelling test, scanning electron microscopy, elemental analysis, and Fourier transform infrared spectroscopy. Ethylene glycol (1.0M) was used as desorption agent. Adsorption studies were performed from hepatitis B surface antibody and anti-hepatitis A antibody positive human plasma. Effects of antibody concentration, contact time, N-methacryloyl-L-tyrosine methyl ester content and temperature on the adsorption capacity were investigated. The amount of hepatitis B surface antibody adsorbed per unit mass increased with increasing hepatitis B surface antibody concentration, then reached saturation. Maximum hepatitis B surface antibody adsorption amount was 21.4 mIU/mg. Adsorption process reached the equilibrium in 60 min. Competitive adsorption of hepatitis B surface antibody, total anti-hepatitis A antibody and total immunoglobulin E was investigated for showing the selectivity. Hepatitis B surface antibody-imprinted particles could adsorb hepatitis B surface antibody 18.3 times more than anti-hepatitis A antibody and 2.2 times more than immunoglobulin E. It can be concluded that hepatitis B surface antibody-imprinted particles have significant selectivity for hepatitis B surface antibody.
