Alpha-smooth muscle actin (ACTA2) serves as a definitive marker for smooth muscle cells and myofibroblasts, making it indispensable for research into vascular biology, fibrosis, wound healing, and epithelial-to-mesenchymal transition. This cytoskeletal protein plays critical roles in contractile function and is frequently upregulated in pathological conditions including organ fibrosis and tumor stroma remodeling, positioning it as a key target for both basic research and translational studies.
This recombinant rabbit monoclonal antibody (clone 6E11) offers the reproducibility that demanding experimental workflows require. Because recombinant production ensures a sequence-defined, consistent reagent across lots, researchers can confidently compare results across extended studies without the variability often encountered with traditional hybridoma-derived antibodies.
Validation data demonstrates robust performance across multiple platforms. Western blot analysis detects ACTA2 in diverse human cell lines including HeLa, HT-29, COLO-205, HEK293, A431, and A375, as well as mouse duodenum tissue, confirming cross-species reactivity with human and mouse samples. The observed band at approximately 45 kDa runs slightly higher than the predicted 42 kDa molecular weight, likely attributes to the mobility deviation of ACTA2 in SDS-PAGE (influence of amino acid composition/conformation) or minor post-translational modifications (such as low-abundance phosphorylation/glycosylation). Immunohistochemistry staining has been validated in human glioma and kidney tissue sections, while immunofluorescence and flow cytometry applications have been confirmed using HepG2 cells, demonstrating clear cytoplasmic localization patterns.
This versatility across western blotting, immunohistochemistry, immunofluorescence, and flow cytometry provides flexibility for researchers investigating smooth muscle differentiation, cancer-associated fibroblasts, or fibrotic disease mechanisms. The antibody arrives purified by affinity chromatography in a glycerol-containing buffer optimized for long-term storage stability.
