A method of producing a stable bacterial preparation having nonspecific immunoglobulinbinding properties. The bacteria, e.g. Staphylococcus aureus or Streptococcus pyogenes, with a nonspecific immunoglobulin-binding component, such as protein A of Staphylococcus aureus, on the surface of the bacteria, are grown in a substrate wherein the bacteria form the immunoglobulinbinding component. Then the bacteria are killed and lyophilized, the lyophilization step being carried out soon after killing of the bacteria. After reconstitution the lyophilized bacteria are used as reagent in immunological reactions. |
