Anti-Streptococcus Group A Antibody

Raised in goat and affinity-matured to recognise the type-specific carbohydrate of group A Streptococcus, this IVD-grade polyclonal reagent from Antibodies.com is supplied as an unconjugated, immunoaffinity-purified preparation at ≥95% purity. The antibody is formulated in 10 mM phosphate-buffered saline at pH 7.2 with 0.1% sodium azide as a preservative, and is validated for ELISA, immunofluorescence assay (IFA), and Western blot workflows, making it well-suited to routine serology and confirmatory workups where Strep A carbohydrate detection is required. Cross-reactivity testing confirms that the reagent does not recognise other streptococcal groups, supporting its use as a group-specific detection tool, and the liquid polyclonal format simplifies direct incorporation into existing lateral flow, plate-based, or blot-based assays. Short-term storage at +4 °C is recommended, with aliquoting and storage at –20 °C advised for long-term stability and to limit freeze/thaw cycles. The 500 µL pack size provides ample volume for high-throughput screening campaigns, and the unconjugated format allows end users to conjugate the antibody to biotin, HRP, or fluorophores of their choice. Distributed through the AFMS supply network, this Antibodies.com primary antibody offers a dependable, lot-to-lot consistent option for laboratories developing or running Streptococcus pyogenes diagnostic and research assays.
