Anti-SPA17 Antibody

This rabbit polyclonal antibody targets SPA17 (Sperm Protein Antigen 17), a cancer-testis antigen whose normal expression is largely restricted to testicular germ cells and spermatozoa. Aberrant re-expression of SPA17 has been documented in multiple myeloma, ovarian carcinoma, and several other malignancies, which is why this reagent is used in oncology and reproductive biology research workflows. The product ships as 50 µl of unconjugated IgG in a single-use vial, allowing direct labeling in custom detection assays and downstream secondary-antibody applications.

Validated for Western blot, the reagent has been tested on human, mouse, and rat samples, supporting translational studies that compare normal tissue expression with tumor-derived material. Researchers investigating testis-specific signaling, sperm surface protein biology, or SPA17 reactivation as a tumor-associated marker will find the polyclonal format useful for recognizing multiple epitopes on the target protein. Each lot is produced by Antibodies.com under controlled host species (rabbit) and clonality (polyclonal) specifications to support reproducible immunoblotting results.
