Anti-Streptococcus pneumoniae Antibody

Sourced from the Antibodies.com catalogue, this primary antibody is a mouse monoclonal reagent raised against Streptococcus pneumoniae and purified from mouse ascites by protein A chromatography. Supplied at 1 mg in an unconjugated, protein A-purified format, the IgG3 isotype clone recognises the Streptococcus pneumoniae common C-polysaccharide (phosphorylcholine epitope), giving it strong utility in immunoassays. Validated uses include ELISA and IFA, where it has been used to detect whole pneumococci as well as the species-specific C-polysaccharide antigen. The host species is mouse, the clonality is monoclonal, and the conjugate is unconjugated, making it a flexible building block for laboratories that need to attach their own reporter enzymes, fluorophores or beads. Because reactivity is directed against a bacterial target, the reagent is classed as an IVD-grade antibody intended for microbiological and infectious-disease workflows, including the detection of Streptococcus pneumoniae antigens in clinical and research samples. The product is provided as a liquid monoclonal antibody preparation, and like other Antibodies.com mouse monoclonals of the IgG3 subclass it is shipped with a recommended isotype control (Mouse IgG3 [PPV-07], A86748) to support background subtraction in ELISA and IFA experiments. Recommended storage is at2–8 °C for short-term use and –20 °C for long-term stability, with the antibody intended for use in Streptococcus pneumoniae detection assays and related C-polysaccharide antigen work.
