The BD BBL™ Streptocard™ enzyme latex test kits, provides a rapid platform for the serological identification of beta-haemolytic streptococci belonging to Lancefield groups A, B, C, D, F and G.
- Materials are supplied ready for use
- All kit components should be stored at 2 to 8 °C
- Do not freeze
- For in vitro diagnostic use
The grouping method involves enzymatic extraction of group specific carbohydrate antigens. The strep enzyme extraction reagent provided in the kit contains lytic enzymes able to extract the streptococcal group specific antigens with incubation at 37 °C. The extracts can be easily identified using blue polystyrene latex particles sensitized with purified group specific rabbit immunoglobulins. These blue latex particles agglutinate very strongly in the presence of homologous antigen and will not agglutinate when homologous antigen is absent.
BD BBL™ Streptocard™ enzyme latex test kits: Each dropper bottle contains 2.5 ml of blue latex particles coated with purified rabbit antibodies to Lancefield groups A, B, C, D, F or G streptococci. The blue latex particles are suspended in a pH 7.4 buffer containing 0.098% sodium azide as a preservative.
BD BBL™ Streptocard™ enzyme positive control: One dropper bottle containing 2.5 ml of ready to use polyvalent antigens extracted from inactivated streptococci of Lancefield groups A, B, C, D, F and G. The antigens are suspended in a pH 7.4 buffer containing 0.098% sodium azide as a preservative.
BD BBL™ Streptocard™ extraction enzyme: One bottle containing 22 ml of ready to use enzyme extraction reagent with preservative.
Delivery information: Test cards, mixing sticks, instructions for use will be supplied.
