PathoDxtra Strep Grouping Reagent Set (Mfr. No. DR0710M): Extraction Reagent 1 - 4mL; Extraction Reagent 2 - 4mL; Extraction Reagent 3 - 2 x 10mL; Mixing Sticks, Disposable Reaction Cards; For use with selected, separately purchased PathoDxtra Strep Grouping latex reagents
The latex particles of the PathoDxtra grouping reagents are coated in relevant specific antibodies. These react with any corresponding Streptococcal group antigen extracted from the bacterial cell wall, causing agglutination. The test works with as little as one, but up to four, colonies of an 18 to 24 hour culture of β-hemolytic Streptococcal isolates. Rapid reactions are due to group-specific antigen being extracted instantaneously using the room-temperature, nitrous acid extraction procedure. Once neutralized, the extracted antigen is tested against specific IgG-coated latex particles on a test slide. The distinct and easily recognizable granular agglutination pattern of a positive test contrasts markedly with the uniform, milky appearance of a negative result, making the test simple to interpret.
