Product Overview
This rabbit polyclonal antibody targets melanocyte protein PMEL in human, mouse and rat samples and is validated for Western blot. The predicted molecular weight is 70.3 kDa, and the supplier reports an observed band at about 80 kDa.
PMEL (also called gp100 or Pmel17) is a melanocyte transmembrane protein whose processed fragments form functional amyloid fibrils inside melanosomes. These fibrils shape early melanosomes and provide a scaffold for melanin deposition, and gp100 is also a well-known melanoma antigen used in pathology and immunotherapy research.

Validated Applications
| Western blot | 0.1–0.5 µg/mL (Human, Mouse, Rat) |
|---|
Samples with a confirmed band (WB): human A2058 cells, rat testis tissue, rat C6 cells, mouse testis 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.
Immunogen
Synthetic peptide from the N-terminal region of human melanoma gp100/PMEL. Sequence identity with the mouse and rat orthologs: 71.4% and 65.7%, respectively.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places melanocyte protein PMEL in the endoplasmic reticulum membrane, endosome, melanosome and extracellular vesicle. Tissue expression noted by UniProt (human): Normally expressed at low levels in quiescent adult melanocytes but overexpressed by proliferating neonatal melanocytes and during tumor growth. 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).
