Product Overview
Clone 18U88 is a rabbit monoclonal antibody that recognizes ubiquitin carboxyl-terminal hydrolase 9X (gene USP9X) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF and flow cytometry. The predicted molecular weight is 292.3 kDa, and the supplier reports an observed band at about 292 kDa.
USP9X is a large X-linked deubiquitinating enzyme that protects many proteins from proteasomal degradation. Its substrates include SMAD4, whose deubiquitination supports TGF-β/BMP signaling, and the survival protein MCL1. USP9X is studied in development, neurodevelopment and cancer.

Samples with a confirmed band (WB): human SIHA cells, human A549 cells, rat brain tissue, mouse liver tissue, mouse brain tissue.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 8% SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 1:500 overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): human testis cancer tissue, mouse liver tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in EDTA buffer (pH 8.0).
Immunogen
Synthetic peptide based on the sequence of human USP9x.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places ubiquitin carboxyl-terminal hydrolase 9X in the cytoplasm and cell projection. Tissue expression noted by UniProt (human): Widely expressed in embryonic and adult tissues. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
