Glycoprotein 9 functions as a structural subunit that stabilizes the GPIbalpha receptor, enabling platelet interaction with von Willebrand factor under high shear conditions. The Glycoprotein 9 antibody is widely used in hematology and cardiovascular research to study platelet function, coagulation, and bleeding disorders.\u003cbr\u003e\u003cbr\u003eThe protein is encoded by the GP9 gene on human chromosome 3q21.3. Glycoprotein 9 is approximately 177 amino acids long and contains a single leucine-rich repeat flanked by cysteine-rich regions, which maintain receptor conformation and complex assembly. It is expressed exclusively on platelet membranes and megakaryocytes, where it associates non-covalently with GPIbalpha and GPIbbeta to form the functional receptor complex for von Willebrand factor binding.\u003cbr\u003e\u003cbr\u003eThe Glycoprotein 9 antibody detects a 25 kilodalton band by western blot and shows strong membrane staining in platelets. The GPIb-IX-V complex mediates platelet tethering to exposed subendothelial matrix at sites of vascular injury, initiating platelet activation and aggregation. Defects or mutations in Glycoprotein 9 lead to Bernard-Soulier syndrome, characterized by thrombocytopenia, giant platelets, and impaired adhesion.\u003cbr\u003e\u003cbr\u003eBeyond hemostasis, the GPIb-IX-V complex participates in inflammatory and immune signaling. Platelet Glycoprotein 9 contributes to leukocyte recruitment, vascular permeability, and thromboinflammatory responses. Overexpression or dysregulation has been associated with thrombosis and cardiovascular disease, making it an important target for antithrombotic therapy.\u003cbr\u003e\u003cbr\u003eBecause of its role in platelet adhesion and vascular integrity, Glycoprotein 9 is a critical biomarker for platelet-related disorders.\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\u003eImmunohistochemistry:\u003c\/strong\u003e map target signal in tissue context and compare regions\/phenotypes.\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=GP9 - NCBI Gene search — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=GP9 - Ensembl search — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=GP9 - Human Protein Atlas search — HPA — https:\/\/www.proteinatlas.org\/search\/GP9 - PubMed (review) — NLM — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=GP9+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":53047294591341,"sku":"FY12598","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_be34731c-f10a-40c7-bed6-3f0ec263a721.jpg?v=1782237020","url":"https:\/\/www.ebiohippo.com\/products\/glycoprotein-9-antibody-gp9-cd42a-bha17135501","provider":"BioHippo","version":"1.0","type":"link"}
