Thermo Scientific™ Streptex Latex Group C

Description

Supplement the reagents in Thermo Scientific™ Remel™ Streptex™ Latext Agglutination Kit with Thermo Scientific Remel Streptex Latex Group C. Streptex Latex Agglutination Kit is a rapid latex test used to detect and identify the Lancefield Groups of streptococci A, B, C, D, F and G and contains all components necessary for the system. The test utilizes latex particles sensitized with group-specific antibodies which agglutinate in presence of homologous antigens.

Streptococci can be generally classified as alpha, beta, or gamma based on their hemolytic reactions indicated by appearance of zones around colonies growing on blood agar. Beta-hemolytic streptococci are further characterized by Lancefield groups.

Most Streptococci possess group-specific antigens which are usually carbohydrate structural components of the cell wall. Lancefield showed that these antigens can be extracted in soluble form and identified by precipitation reactions with homologous antisera¹. Polystyrene latex particles coated with group-specific antibodies agglutinate strongly in the presence of homologous antigen and remain in smooth suspension in the absence of homologous antigen.

• Ready to use: Latex suspension is supplied as a ready-to-use reagent.
• Economical solution: Maximize spending efficiency with the option of purchasing separate kit components.
• Color-coded reagent: Pink cap.

Streptex Latex Group C reagent contains latex specific for group C, sufficient for up to 50 tests, supplied in single plastic dropper bottles. The polystyrene latex particles coated with purified rabbit antibody to the group C antigen are suspended at a concentration of 0.5% in phosphate buffer (pH 7.4) containing 0.1% sodium azide as preservative.
