Anti-SSX5 Antibody

Raised in rabbit as an unconjugated polyclonal IgG, this primary antibody from Antibodies.com targets SSX5, a cancer/testis antigen encoded within the synovial sarcoma X breakpoint repeat on chromosome Xq28. The reagent is supplied at 50 µl per vial and validated for western blot, immunohistochemistry, and immunofluorescence on human, mouse, and rat specimens, enabling comparative work across cell lines, xenograft models, and patient-derived tumor samples for research use only. Because SSX5 normally shows restricted expression in testicular germ cells but is reactivated across multiple solid tumor types, the antibody is used to characterize aberrant transcriptional regulation and to evaluate candidate antigens for tumor immunotherapy. Polyclonal epitope coverage supports recognition of multiple SSX5 isoforms and is compatible with denaturing gels as well as formalin-fixed paraffin-embedded tissue sections. For long-term activity, aliquot on first use and store at -20 °C protected from light, minimizing freeze-thaw cycles; refrigerated handling is appropriate during active protocols. The unconjugated format permits flexible pairing with user-selected secondary reagents and label chemistries tailored to specific western blot, IHC, or IF workflows.
