1. in yolk, extract a method of γ

  • -livitin (IgY), comprising;

    A) provide a buffering saline solution, a yolk sample and an inorganic salts;

    B) use this this yolk sample of buffering salt solution dilution, stir after the scheduled time, centrifugal to obtain a supernatant liquor;

    AndC) use this inorganic salts to carry out salt precipitation to this supernatant liquor, to obtain one γ

    -livitin;

    Wherein, the pH value of this buffering saline solution is in 4.6 to 5.4 scopes, and the concentration of this buffering saline solution is in 0.05M to 0.15M scope, and the saturation ratio of this inorganic salts is 30% to 60%.
