Product Overview
This rabbit polyclonal antibody detects prohibitin 1 (gene PHB1) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF and ELISA. The predicted molecular weight is 29.8 kDa, and the supplier reports an observed band at about 30 kDa.
Prohibitin 1 (PHB1, PHB) is a highly conserved protein that forms large ring complexes with prohibitin 2 in the inner mitochondrial membrane. These complexes act as scaffolds and chaperones that stabilize respiratory chain subunits and maintain mitochondrial structure. PHB1 also has reported roles at the plasma membrane and in the nucleus as a transcriptional co-regulator.

Samples with a confirmed band (WB): human Caco-2 cells, human 293T cells, human HepG2 cells, human A549 cells, rat heart tissue, rat liver tissue, mouse heart tissue, mouse liver tissue.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 10% 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 colon cancer tissue, human lung 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 confirmed staining (ICC/IF): A549 cells.
Immunogen
Recombinant human Prohibitin/PHB fragment (Met1–Ile257), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places prohibitin 1 in the mitochondrion inner membrane, nucleus, cytoplasm and cell membrane. Tissue expression noted by UniProt (human): Widely expressed in different tissues. 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).
