Anti-Salmonella paratyphi A Antibody

This mouse monoclonal reagent from Antibodies.com targets the somatic lipopolysaccharide antigens of Salmonella paratyphi A, a Gram-negative enteric pathogen responsible for paratyphoid fever in humans. Produced as an IgG3 isotype antibody and purified by Protein A chromatography, the unconjugated preparation is supplied at 1 mg per vial and is validated for ELISA and IFA workflows in clinical microbiology, food safety testing, and outbreak investigation laboratories. The antibody binds to the O-antigen determinants that distinguish S. paratyphi A from related serovars such as S. typhi and S. paratyphi B, supporting serogroup identification in cultured isolates and slide agglutination protocols. Researchers working on enteric disease surveillance, vaccine development, and diagnostic assay design rely on serovar-specific reagents like this one to confirm isolates recovered from blood, stool, or environmental samples. For short-term use, aliquot and refrigerate the vial; for longer storage, keep frozen in single-use aliquots to limit freeze-thaw damage to the IgG3 protein.
