Abstract
A method for the separation of IgG and IgA from an immunoglobulin-containing starting material is described, whereby the method is characterized in that (i) IgG and optionally IgA are adsorbed to a solid inorganic carrier material, (ii) IgA is isolated from the eluate, optionally after selective desorption, whereas IgG remains on the carrier material, and optionally (iii) IgG is isolated from the adsorbate. Furthermore, an IgA preparation is disclosed which demonstrates a low tendency to form aggregates.
