The UniProt recommended name is Transmembrane glycoprotein NMB (GPNMB). Also known as Osteoactivin or HGFN, this glycoprotein is expressed in osteoclasts, melanocytes, macrophages, and tumor cells, where it contributes to cell signaling and microenvironment remodeling.\u003cbr\u003e\u003cbr\u003eFunctionally, GPNMB antibody identifies a 560-amino-acid glycoprotein with an extracellular domain containing an RGD-like integrin-binding motif, a transmembrane helix, and a short cytoplasmic tail with a tyrosine-based sorting signal. GPNMB facilitates cell-matrix interaction and promotes osteoblast differentiation, pigment cell function, and immune modulation. It is also upregulated during tissue repair and inflammation, reflecting its role in regeneration and immune regulation.\u003cbr\u003e\u003cbr\u003eThe GPNMB gene is located on chromosome 7p15.2 and encodes a protein expressed in bone, skin, brain, and immune cells. In macrophages and dendritic cells, GPNMB modulates cytokine release and antigen presentation, while in osteoclasts it contributes to bone resorption and remodeling. The protein undergoes ectodomain shedding, releasing soluble fragments that influence neighboring cells.\u003cbr\u003e\u003cbr\u003ePathologically, GPNMB is overexpressed in several cancers, including melanoma, breast, and glioma, where it promotes migration, invasion, and angiogenesis. It also plays roles in neurodegenerative diseases and inflammation. Because of its surface localization, GPNMB serves as a potential therapeutic target and biomarker. Research using GPNMB antibody supports studies of tumor biology, osteogenesis, and immune signaling.\u003cbr\u003e\u003cbr\u003eGPNMB antibody is suitable for western blotting, immunohistochemistry, and flow cytometry to detect membrane-associated and soluble GPNMB. \u003cbr\u003e\u003cbr\u003eStructurally, Transmembrane glycoprotein NMB features multiple N-glycosylation sites contributing to stability and cell-surface expression. The cytoplasmic domain interacts with intracellular adaptors, linking extracellular signals to intracellular pathways. This antibody enables detection of GPNMB in studies of cell communication, repair, and disease progression.\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=GPNMB - NCBI Gene search — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=GPNMB - Ensembl search — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=GPNMB - Human Protein Atlas search — HPA — https:\/\/www.proteinatlas.org\/search\/GPNMB - PubMed (review) — NLM — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=GPNMB+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":53047312318829,"sku":"FY13098","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_b6274a0a-fceb-430b-b592-b6dc662e8b91.jpg?v=1782237093","url":"https:\/\/www.ebiohippo.com\/products\/gpnmb-antibody-transmembrane-glycoprotein-nmb-hgfn-bha17136000","provider":"BioHippo","version":"1.0","type":"link"}
