The encoded protein, alpha actin (ACTA2), is an isoform of actin expressed primarily in vascular and visceral smooth muscle. As a major component of the contractile apparatus, ACTA2 plays a central role in generating force for smooth muscle contraction and maintaining structural integrity of the cytoskeleton.\u003cbr\u003e\u003cbr\u003eAlpha actin is abundantly expressed in smooth muscle cells of the vasculature, airways, gastrointestinal tract, and reproductive system. It is also used as a marker of myofibroblast differentiation, where its upregulation reflects tissue remodeling during wound healing, fibrosis, and pathological scarring. Because of its strong and specific expression pattern, detection with ACTA2 antibody is widely applied in immunohistochemistry and immunofluorescence to identify smooth muscle or myofibroblastic cells in tissue samples.\u003cbr\u003e\u003cbr\u003eIn cardiovascular research, ACTA2 is studied as a marker of vascular smooth muscle cells and their phenotypic switching. Under pathological conditions such as atherosclerosis or hypertension, ACTA2 expression can change as smooth muscle cells adopt synthetic phenotypes. In pulmonary and hepatic fibrosis, ACTA2 positive myofibroblasts contribute to extracellular matrix deposition and tissue stiffening, making ACTA2 a reliable indicator of fibrotic remodeling.\u003cbr\u003e\u003cbr\u003eStructurally, alpha actin is a globular protein that polymerizes into filamentous actin, forming part of the cytoskeleton. ACTA2 interacts with actin binding proteins to regulate filament dynamics, cell shape, and motility. Its high conservation across species ensures that ACTA2 antibody is effective in many experimental systems, including human and animal models.\u003cbr\u003e\u003cbr\u003eThe ACTA2 antibody is commonly used in western blotting, immunohistochemistry, immunofluorescence, and flow cytometry. These applications enable researchers to assess expression, distribution, and structural changes of smooth muscle actin in both healthy and diseased tissues. For scientists investigating vascular biology, fibrosis, tissue remodeling, or smooth muscle physiology, the ACTA2 antibody provides a sensitive and specific detection tool.\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\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 Monoclonal antibodies provide a defined epitope recognition profile that can support consistent comparisons across experiments.\u003c\/p\u003e\u003c!-- Sources (internal): - UniProt search — UniProt — https:\/\/www.uniprot.org\/uniprotkb?query=ACTA2 - NCBI Gene search — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=ACTA2 - Ensembl search — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=ACTA2 - Human Protein Atlas search — HPA — https:\/\/www.proteinatlas.org\/search\/ACTA2 - PubMed (review) — NLM — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=ACTA2+review --\u003e","brand":"NSJ Bioreagents","offers":[{"title":"Antibody in PBS with 0.02% sodium azide, 50% glycerol and 0.4-0.5mg\/ml BSA \/ 100 ul","offer_id":53047327359341,"sku":"RQ8952","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_dcb96811-0820-444c-9688-098ac10f533c.jpg?v=1772019451","url":"https:\/\/www.ebiohippo.com\/products\/acta2-antibody-alpha-actin-smooth-muscle-actin-bha17136370","provider":"BioHippo","version":"1.0","type":"link"}
