Product Overview
This rabbit polyclonal antibody targets transmembrane protease serine 3 (gene TMPRSS3) in human, mouse and rat samples and is validated for Western blot, IHC, flow cytometry and ELISA. The predicted molecular weight is 49.4 kDa, and the supplier reports an observed band at about 48 kDa.
TMPRSS3 is a type II transmembrane serine protease expressed in the inner ear. It is needed for the survival of cochlear hair cells around the onset of hearing and can activate the epithelial sodium channel ENaC in vitro. Mutations in TMPRSS3 cause autosomal recessive nonsyndromic hearing loss.

Validated Applications
| Western blot | 0.25–0.5 µg/mL (Human, Mouse, Rat) |
|---|---|
| IHC (paraffin sections) | 2–5 µg/mL (Human, Mouse, Rat) |
| Flow cytometry (fixed cells) | 1–3 µg/1×106 cells (Human) |
| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): human MCF-7 cells, human HepG2 cells, rat pancreas tissue, rat stomach tissue, rat PC-12 cells, mouse lung tissue, mouse RAW264.7 cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): human gastric cancer tissue, mouse brain tissue, rat brain tissue, human ovarian cancer 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).
Samples with a confirmed signal (flow cytometry): A431 cells.
Immunogen
Recombinant human TMPRSS3 fragment (Glu3–Thr454), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places transmembrane protease serine 3 in the endoplasmic reticulum membrane. Tissue expression noted by UniProt (human): Expressed in many tissues including fetal cochlea. The samples tested by the supplier (listed above) are a practical starting point for positive controls.

Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
