  • Process for isolating IgG and IgA
    Patent number: 6646108
    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.

  • Composition and method for preventing and treating inflammation with Immunoglobulin A
    Patent number: 5833984
    Abstract: Inflammation can be treated or prevented altogether by administering a preparation comprising IgA. These preparations also can effect immunomodulation. Preferably, the preparation includes multimeric IgA and is essentially free of IgG in its various forms. Other compounds, such as antibiotics, antiphlogistic agents and antacids, also may be administered. Immunoglobulin A may also be used in vaccines to prevent inflammation. Additionally, an improved assay for evaluating anti-inflammatory activity is provided.

  • Virus-safe monomeric human immunoglobulin A and methods for its production
    Patent number: 5808000
    Abstract: A virus-safe monomeric human IgA is described which is essentially free of IgG. The IgA according to the invention is obtainable according to a process in which (a) an IgA-containing fraction is subjected to a purification such that a monomeric IgA which is essentially free of IgG is obtained and (b) the obtained product is subjected to a process for the inactivation of viruses.
