About this item
The Prolex™ Streptococcal Xtra Select Kit provides a rapid platform for the serological identification of beta-haemolytic streptococci belonging to Lancefield groups A and B.
- Able to extract streptococcal group specific antigens at room temperature
- Easily identify extracts
- Reagent contains a proprietary formulation of lytic enzymes
The routine quality control procedure for each Prolex™ lot involves testing blue latex reagents and Streptococcal Xtra Extraction Reagent with each streptococcal group A and B using the ATCC strains or equivalent as listed in this section
The Prolex™ Streptococcal Xtra Select Kit grouping method involves enzymatic extraction of group specific carbohydrate antigens using specially selected lytic enzymes. The Streptococcal Xtra Extraction Reagent provided in the kit contains a proprietary formulation of lytic enzymes able to extract streptococcal group specific antigens at room temperature. Extracts can be easily identified using blue polystyrene latex particles sensitized with purified group specific rabbit immunoglobulins. These blue latex particles agglutinate strongly in the presence of homologous antigen and will not agglutinate when homologous antigen is absent.
The extract from these strains will agglutinate with the homologous latex reagent. The Polyvalent Positive Control is used to test the individual latex reagents.
