Key elements and design rationale
- Antibody format: Rabbit Polyclonal Rabbit IgG
- Immunogen / epitope context: A synthetic peptide corresponding to a sequence at the N-terminus of human Melanoma gp100/PMEL, which shares 71.4% and 65.7% amino acid (aa) sequence identity with mouse and rat Melanoma gp100/PMEL, respectively.
- Molecular weight context: reported MW: 80 kDa; calculated MW: nan
- Reactivity: Human,Mouse,Rat
- Applications: Flow Cytometry, IF, IHC, WB
As a polyclonal antibody, the reagent recognizes multiple epitopes on the target, which can improve detection robustness but may increase sensitivity to sample-dependent epitope changes.
Biological background
premelanosome protein. This gene is mapped to 12q13.2. It encodes a melanocyte-specific type I transmembrane glycoprotein. The encoded protein is enriched in melanosomes, which are the melanin-producing organelles in melanocytes, and plays an essential role in the structural organization of premelanosomes. This protein is involved in generating internal matrix fibers that define the transition from Stage I to Stage II melanosomes. This protein undergoes a complex pattern of prosttranslational processing and modification that is essential to the proper functioning of the protein. A secreted form of this protein that is released by proteolytic ectodomain shedding may be used as a melanoma-specific serum marker. Alternate splicing results in multiple transcript variants. Functional note: Plays a central role in the biogenesis of melanosomes. Involved in the maturation of melanosomes from stage I to II. The transition from stage I melanosomes to stage II melanosomes involves an elongation of the vesicle, and the appearance within of distinct fibrillar structures. Release of the soluble form, ME20-S, could protect tumor cells from antibody mediated immunity. Reported localization: multivesicular body. Endoplasmic reticulum membrane. Single-pass type I membrane protein. Golgi apparatus. Melanosome. Secreted. Expression/tissue context: Preferentially expressed in melanomas. Some expression was found in dysplastic nevi. Not found in normal tissues nor in carcinomas. Normally expressed at low levels in quiescent adult melanocytes but overexpressed by proliferating neonatal melanocytes and during tumor growth.

Common research applications
- Western blotting: compare relative PMEL levels across conditions; band patterns may reflect isoforms and processing.
- IHC/IHC-F: assess spatial distribution of PMEL across tissue regions and cell types using matched controls.
- IF/ICC: evaluate subcellular localization and co-localization patterns; signal can depend on fixation/permeabilization and epitope accessibility.
- Flow cytometry: quantify target-positive populations and shifts in expression; gating strategy and background staining controls are essential.
Notes for experimental interpretation
- Specificity notes: No cross reactivity with other proteins.
- Cross-reactivity: No cross-reactivity with other proteins.
- Isoforms and PTMs: Apparent size and signal patterns can differ across splice isoforms, proteolytic processing, and post-translational modifications.
- Controls: Include an isotype control (as relevant), no-primary control for imaging, and orthogonal validation such as KD/KO samples when available.
