[A method of solid-phase analysis of antigens using Staphylococcus aureus as the label]

A new method of solid-phase analysis of viral antigens in which St. aureus, strain Cowan 1, was used as a label is described. The result of analysis is read visually by bacterial agglutination. The degree of agglutination of the staphylococcal diagnosticum corresponds to the amount of the antigen bound with antibodies immobilized on the solid phase. Staining of Staphylococcus with methylene blue simplifies reading of the results. The method has been shown to be sufficiently simple, specific, sensitive, and may be used for diagnosis of different infections diseases.
