Product Overview
This rabbit polyclonal antibody detects presequence protease, mitochondrial (gene PITRM1) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 117.4 kDa, and the supplier reports an observed band at about 117 kDa.
PITRM1 (presequence protease, PreP) is a zinc metalloprotease of the mitochondrial matrix that degrades short peptides, including cleaved mitochondrial targeting presequences. It also degrades amyloid-β peptides that reach mitochondria, and it is studied in mitochondrial proteostasis and neurodegeneration.

Samples with a confirmed band (WB): human A549 cells, human U2OS cells, human placenta tissue, human U-87MG cells, rat lung tissue, rat kidney tissue, mouse lung tissue, mouse kidney tissue.
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 heart tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.

Samples with confirmed staining (ICC/IF): SiHa cells.
Samples with a confirmed signal (flow cytometry): U937 cells.
Immunogen
Recombinant human PITRM1 fragment (Ala33–Lys1037), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places presequence protease, mitochondrial in the mitochondrion matrix. Tissue expression noted by UniProt (human): Widely expressed. 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).
