Thermo Scientific™ Streptex™ Acid Extraction Kit

Description

• Rapidly extract and identify streptococcal Lancefield group antigens from cultured organisms using Thermo Scientific™ Remel™ Streptex™ Acid Extraction Kit in conjunction with the Streptex™ Kit (ZL50/R30950501 and ZL61/R30164701)
• Lancefield showed that group-specific streptococcal antigens can be extracted in soluble form and identified by precipitation reactions with homologous antisera 1
• The Streptex™ kit requires at least 10 minutes incubation at 37°C to extract the group antigen
• Reagents supplied in this kit allow a more rapid extraction of group antigen
• Species of Streptococcus are classified based on their hemolytic properties (alpha and beta)
• Beta-hemolytic streptococci are further classified by Lancefield grouping
• The majority of species of Streptococcus possess group-specific antigens which are usually carbohydrate structural components of the cell wall
• Group-specific antigens are extracted from streptococci by nitrous acid in a simple and short incubation step
• The extract is then neutralised and antigens are detected and identified with suspensions of latex particles coated with group-specific antibodies
• Ready-to-use: R eagent kit Rapid extraction: W ithin 1 minute
• Ease of identification: Positive result is indicated by aggregation of latex particles
• The acid extraction kit provides reagents for the extraction of Lancefield group A, B, C, F and G at room temperature (18 – 30° C)
• Extraction is complete within 1 minute
• Group D antigen cannot be extracted with these reagents
• The latex suspensions for groups A, B, C, D, F and G are supplied in the Streptex™ Kit (ZL50/R30950501 and ZL61/R30164701) or as individual suspensions
