The blue-latex particles used in the StaphTEX™ Blue Latex Reagent are sensitized with specific concentrations of plasma proteins. When coagulase and/or protein A is provided by the culture specimen at detectable levels, they will interact with the sensitized particles to produce visible agglutination/clumping, indicating a positive test for S. aureus. MATERIALS SUPPLIED Blue-latex particles coated with IgG and human 1. fibrinogen. The StaphTEX™ latex particles Blue are suspended Reagent: in a buffer containing 0.098% sodium azide as a preservative. A formulation 2. of non-viable StaphTEX™ S. aureus in a Blue buffer Positive containing 0.1% Control sodium azide Reagent: as a preservative. A formulation of non-viable, 3. StaphTEX™ negative Blue Staphylococcus Negative spp. in a buffer Control containing 0.1% Reagent: sodium azide as a preservative.
