Helicobacter pylori Antigen

Sourced from Antibodies.com, this native Helicobacter pylori antigen is supplied as a ready-to-use liquid extract designed for immunoassay development. Each vial contains 1 mL of a Liquid Antigen Extract formulated in deionized water, presenting the bacterial components in an unconjugated format suitable for direct coating or use as a positive control. The product is validated for ELISA applications and is dispatched from Cambridge, UK, with a typical lead time of 10–14 business days. It is intended strictly for research use only and is not approved for diagnostic or therapeutic purposes. Because the antigen is a native bacterial preparation rather than a recombinant or monoclonal reagent, no host species, clonality, isotype, or conjugate applies to the antigen itself, and reactivity is directed against Helicobacter pylori epitopes recognised in standard serological and stool-antigen-style assay formats. For long-term stability the liquid should be stored frozen according to the supplier's recommended conditions, and the product should be handled under standard microbiology-safety practices since it derives from a bacterial source. Researchers looking for a consistent, well-characterised H. pylori capture or detection reagent for ELISA kit development, internal assay standardisation, or cross-reactivity studies will find this native extract a convenient off-the-shelf option. Pairing it with one of the matching anti-Helicobacter pylori antibodies available through the Antibodies.com catalogue allows users to build complete sandwich or competitive assay configurations from a single supplier.
