LGR5 is essential for maintaining self-renewing adult stem cell populations in the intestine, hair follicle, and stomach. The LGR5 antibody is used in stem-cell biology, oncology, and regenerative medicine to identify proliferative stem cell compartments.\u003cbr\u003e\u003cbr\u003eLGR5 is encoded by the LGR5 gene on human chromosome 12q21.1. The receptor is approximately 907 amino acids long, with seven transmembrane domains typical of GPCRs and a large extracellular region containing leucine-rich repeats that mediate ligand binding. Upon R-spondin binding, LGR5 interacts with Frizzled and LRP5\/6 receptors, amplifying Wnt signaling to sustain stem-cell proliferation.\u003cbr\u003e\u003cbr\u003eThe LGR5 antibody detects a 100-120 kilodalton protein by western blot and exhibits membrane and cytoplasmic localization in proliferative epithelial zones. In the intestine, LGR5 marks crypt base columnar cells capable of regenerating the entire epithelium. In the hair follicle, it labels bulge stem cells responsible for hair cycle renewal.\u003cbr\u003e\u003cbr\u003eLGR5 expression is tightly regulated by Wnt activity and is a key marker for cancer stem cells in colorectal and gastric carcinomas. Overexpression promotes tumor initiation and therapy resistance, while knockdown suppresses proliferation and restores differentiation. The receptor modulates beta-catenin stabilization, transcription of target genes, and maintenance of undifferentiated states.\u003cbr\u003e\u003cbr\u003eBecause of its role in tissue regeneration and cancer stemness, LGR5 is an important biomarker for stem-cell tracking and targeted therapy development.\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\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=LGR5 - NCBI Gene search — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=LGR5 - Ensembl search — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=LGR5 - Human Protein Atlas search — HPA — https:\/\/www.proteinatlas.org\/search\/LGR5 - PubMed (review) — NLM — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=LGR5+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":53047290954093,"sku":"FY12528","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_1bdd3665-0200-4f20-89aa-300e09e4bcb4.jpg?v=1782237007","url":"https:\/\/www.ebiohippo.com\/products\/lgr5-antibody-leucine-rich-repeat-containing-g-protein-coupled-receptor-5-bha17135431","provider":"BioHippo","version":"1.0","type":"link"}
