Treponema pallidum (TpN47) Antigen >98%

A highly purified recombinant antigen preparation intended for syphilis serology research and diagnostic immunoassay development, targeting the 47-kDa membrane lipoprotein of Treponema pallidum. This reagent is supplied by Antibodies.com as a 1 mg unit of purified recombinant protein with purity exceeding 98% as verified by SDS-PAGE. The TpN47 (TmpA) antigen is one of the most immunoreactive membrane proteins of the syphilis spirochete and is widely incorporated into treponemal immunoassays as a sensitive marker of infection. Recommended applications include ELISA and Western blot workflows, where it functions as a coating or capture antigen for detecting anti-treponemal IgG and IgM antibodies in clinical specimens. The recombinant expression format delivers batch-to-batch consistency and removes biosafety concerns associated with native pathogen-derived material. For optimal stability, store at -20°C in working aliquots and avoid repeated freeze-thaw cycles. Intended for research use only.
