MARVELD2 is essential for forming the barrier against paracellular diffusion of macromolecules, thereby preserving tissue polarity and homeostasis. The MARVELD2 antibody is widely used in epithelial biology and cell junction research to study tight junction architecture, permeability control, and barrier dysfunction.\u003cbr\u003e\u003cbr\u003eMARVELD2 is encoded by the MARVELD2 gene located on human chromosome 5q13.1. The protein is approximately 558 amino acids long and contains four transmembrane segments with a cytoplasmic C-terminal tail. It localizes at tricellular tight junctions, distinct from bicellular tight junction proteins such as occludin and claudins. MARVELD2 interacts with angulin family proteins and zonula occludens proteins to anchor the tricellular junction complex to the actin cytoskeleton.\u003cbr\u003e\u003cbr\u003eThe MARVELD2 antibody detects a 65 kilodalton band by western blot and exhibits strong junctional staining along epithelial borders in immunofluorescence. MARVELD2 regulates diffusion barrier properties by sealing the tricellular junction core, ensuring that epithelial sheets restrict large solute movement. Loss of MARVELD2 disrupts paracellular sealing, resulting in barrier leakage and increased susceptibility to inflammation and infection.\u003cbr\u003e\u003cbr\u003eMutations in MARVELD2 cause autosomal recessive deafness (DFNB49) due to impaired tight junction formation in the cochlea, leading to hair cell degeneration and hearing loss. Altered expression is also associated with inflammatory bowel disease and cancer metastasis, where weakened epithelial integrity promotes tissue invasion and immune infiltration.\u003cbr\u003e\u003cbr\u003eAs a critical determinant of epithelial sealing and tissue organization, MARVELD2 serves as a biomarker for tight junction function and epithelial polarity.\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=MARVELD2 - NCBI Gene search — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=MARVELD2 - Ensembl search — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=MARVELD2 - Human Protein Atlas search — HPA — https:\/\/www.proteinatlas.org\/search\/MARVELD2 - PubMed (review) — NLM — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=MARVELD2+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":53047292658029,"sku":"FY12573","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_97638834-8923-4e4a-9349-b5e041162d78.jpg?v=1782237044","url":"https:\/\/www.ebiohippo.com\/products\/marveld2-antibody-tricellulin-bha17135476","provider":"BioHippo","version":"1.0","type":"link"}
