Figure 6: Ratio of IgG and IgM adsorption to fibrinogen absorption measured by column flow adsorption. The ratio of IgG and IgM adsorption to fibrinogen adsorption was evaluated from the mean adsorption rates for IgG, IgM, and fibrinogen obtained using a column flow method with adsorbents containing the 4 thiol compounds and 5 types of amino acids.
