Encoded by the LPXN gene on chromosome 11q12.1, this protein belongs to the paxillin family of LIM domain-containing adaptors that mediate integrin-dependent signaling and actin cytoskeleton rearrangement. LPXN is primarily expressed in hematopoietic and endothelial cells, where it modulates adhesion dynamics, motility, and signal transduction downstream of integrins and growth factor receptors.\u003cbr\u003e\u003cbr\u003eStructurally, Leupaxin is a 395-amino-acid cytoplasmic protein of approximately 46 kilodaltons that contains four C-terminal LIM domains and an N-terminal LD motif region that binds focal adhesion kinase (FAK), PYK2, and other adhesion regulators. These motifs allow LPXN to function as a scaffold linking structural proteins, tyrosine kinases, and cytoskeletal components at focal adhesions. Its phosphorylation on tyrosine residues by FAK and Src family kinases regulates recruitment to adhesion complexes and determines downstream signaling strength.\u003cbr\u003e\u003cbr\u003eThe LPXN antibody is widely used in cell biology, immunology, and cancer research to study integrin-mediated signaling, immune cell migration, and cytoskeletal regulation. Western blot analysis detects a 46 kilodalton band corresponding to Leupaxin, while immunofluorescence shows punctate cytoplasmic and peripheral staining consistent with focal adhesion localization. This antibody supports studies examining adhesion turnover, cell spreading, and mechanotransduction in immune and endothelial systems.\u003cbr\u003e\u003cbr\u003eFunctionally, LPXN modulates adhesion strength and migratory capacity in leukocytes and macrophages by coordinating the FAK\/PYK2 and paxillin signaling pathways. It influences podosome formation, phagocytosis, and chemotaxis through its ability to regulate actin polymerization and integrin clustering. Dysregulated LPXN expression has been linked to cancer metastasis, inflammatory disorders, and defective immune cell trafficking. The LPXN antibody provides a reliable tool for evaluating these processes and understanding how adhesion adaptors control immune cell behavior.\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\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=LPXN - NCBI Gene search — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=LPXN - Ensembl search — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=LPXN - Human Protein Atlas search — HPA — https:\/\/www.proteinatlas.org\/search\/LPXN - PubMed (review) — NLM — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=LPXN+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":53047305830765,"sku":"FY12903","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_0fe31938-ddf2-435c-90af-872ef32d5c7f.jpg?v=1782237052","url":"https:\/\/www.ebiohippo.com\/products\/lpxn-antibody-leupaxin-bha17135805","provider":"BioHippo","version":"1.0","type":"link"}
