• Validate your test procedures with Thermo Scientific™ Remel™ Streptex™ Positive Control
• Streptex is a rapid latex test system 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
• Streptex Positive Control reagent is polyvalent positive control supplied as an accessory for the Streptex kit
• 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 antisera 1
• 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
• The extraction enzyme used is freeze-dried proteolytic fraction obtained from Streptomyces griseus cultures, containing calcium chloride
• Ready to use - Latex suspension is supplied as Ready to use reagent Economical solution - Maximize spending efficiency with the option of purchasing separate kit components Color-coded reagent - Red cap Streptex Polyvalent Positive Control reagent contains a polyvalent extract of antigens from a representative strain of each streptococcal group A, B, C, D, F and G, supplied in single plastic dropper bottles
