The UniProt recommended name is Premelanosome protein (PMEL). Also known as SILV, gp100, or ME20, this glycoprotein forms amyloid fibrils that serve as scaffolds for melanin polymerization within developing melanosomes.\u003cbr\u003e\u003cbr\u003eFunctionally, PMEL antibody identifies a 661-amino-acid type I transmembrane glycoprotein synthesized in melanocytes. PMEL is cleaved by proprotein convertases into M alpha and M beta fragments, which assemble into amyloid fibrils in stage II melanosomes. These fibrils provide a matrix for eumelanin deposition, enabling proper pigment granule maturation.\u003cbr\u003e\u003cbr\u003eThe PMEL gene is located on chromosome 12p13.31 and is expressed exclusively in pigment-producing cells, including melanocytes and retinal pigment epithelium. PMEL expression is regulated by the transcription factor MITF and is upregulated during melanocyte differentiation. It plays a central role in pigment biogenesis and melanosome architecture.\u003cbr\u003e\u003cbr\u003ePathologically, PMEL is a target antigen in melanoma immunotherapy and an established marker for melanocytic tumors. Mutations in PMEL can cause pigment dilution phenotypes in animals due to altered fibril formation. Research using PMEL antibody supports studies in pigmentation biology, melanoma diagnostics, and organelle structure.\u003cbr\u003e\u003cbr\u003ePMEL antibody is validated for immunohistochemistry, western blotting, and immunofluorescence to detect melanosomal structural proteins. \u003cbr\u003e\u003cbr\u003eStructurally, Premelanosome protein contains an N-terminal signal peptide, a polycystic kidney disease-like (PKD) domain, and a transmembrane domain. Its cleaved fragments aggregate to form functional amyloid fibrils. This antibody supports detailed examination of PMEL's role in melanosome assembly and pigmentation control.\u003c\/div\u003e\u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eConnecting protein-level changes to phenotype using orthogonal readouts (genetic perturbation, transcriptomics, imaging).\u003c\/li\u003e\n\u003cli\u003eConsidering isoforms and post-translational regulation when interpreting protein-level changes.\u003c\/li\u003e\n\u003cli\u003eComparing results across species and model systems with matched controls.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWestern blotting:\u003c\/strong\u003e compare relative abundance and activation-state changes across conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImmunofluorescence:\u003c\/strong\u003e visualize subcellular distribution and cell-to-cell heterogeneity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImmunohistochemistry:\u003c\/strong\u003e map target signal in tissue context and compare regions\/phenotypes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow cytometry:\u003c\/strong\u003e quantify target-positive populations and signal shifts at single-cell resolution.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eELISA:\u003c\/strong\u003e support antibody-based quantification in assay formats where applicable.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eInterpret changes in signal alongside appropriate controls and, when relevant, in parallel with total-protein or pathway readouts.\u003c\/p\u003e\u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eSignal can reflect expression level, isoform composition, and post-translational state; interpret results in the context of your model system and stimuli.\u003c\/li\u003e\n\u003cli\u003eSpecies differences and sample matrices can influence epitope recognition; prioritize matched controls and orthogonal confirmation when feasible.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eAntibody notes:\u003c\/strong\u003e Polyclonal antibodies recognize multiple epitopes, which can broaden the epitope footprint and may increase sensitivity in some contexts.\u003c\/p\u003e\u003c!-- Sources (internal): - UniProt search — UniProt — https:\/\/www.uniprot.org\/uniprotkb?query=PMEL - NCBI Gene search — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=PMEL - Ensembl search — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=PMEL - Human Protein Atlas search — HPA — https:\/\/www.proteinatlas.org\/search\/PMEL - PubMed (review) — NLM — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=PMEL+review --\u003e","brand":"NSJ Bioreagents","offers":[{"title":"Adding 0.2 ml of distilled water will yield a concentration of 500 ug\/ml \/ 100 ug","offer_id":53047313662317,"sku":"FY13157","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_21b7c47b-44be-41a3-b91c-879ad70a8224.jpg?v=1782237096","url":"https:\/\/www.ebiohippo.com\/products\/pmel-antibody-premelanosome-protein-silv-bha17136059","provider":"BioHippo","version":"1.0","type":"link"}
