Anti-PI-9 Antibody

Raised in rabbit and affinity-purified by epitope-specific chromatography, this polyclonal reagent from Antibodies.com targets the intracellular serpin SERPINB9 (also known as PI-9, PI9 or Serpin B9), a granzyme B inhibitor linked to immune evasion and cytotoxic lymphocyte regulation. The antibody was generated against a synthesized peptide derived from the internal region of human PI-9, and the IgG preparation is supplied unconjugated in liquid form (PBS with 50% glycerol, 0.5% BSA and 0.02% sodium azide) at a protein concentration of approximately 1 mg/mL. Each vial contains 50 µL, with a 100 µL format also offered on the supplier's catalogue page. Endogenous PI-9 is detected in human, mouse and rat samples, and the reagent has been validated for Western blotting, immunohistochemistry and ELISA applications. For routine use the supplier recommends aliquoting on arrival and storing at -20 °C, avoiding repeated freeze/thaw cycles, with the product shipped at 4 °C to maintain stability. Researchers working on cytotoxic T-cell biology, tumor immunology or protease inhibitor studies will find this Antibodies.com polyclonal a consistent and versatile tool for cross-species detection of SERPINB9 in lysates and tissue sections.
