WNT3A抗体

The WNT3A antibody is a crucial tool in studying the Wnt/β-catenin signaling pathway, which plays a pivotal role in embryonic development, tissue homeostasis, and cell fate regulation. WNT3A, a secreted glycoprotein, acts as a ligand that binds to Frizzled receptors and LRP co-receptors, initiating downstream signaling cascades. Dysregulation of WNT3A is linked to developmental disorders, cancer progression, and stem cell maintenance. Antibodies targeting WNT3A are widely used in research to detect protein expression, assess localization (via techniques like Western blot, immunohistochemistry, or immunofluorescence), and modulate signaling activity in experimental models. Polyclonal and monoclonal variants exist, with specificity validated across species such as human, mouse, and rat. These antibodies aid in exploring WNT3A's role in diseases like colorectal cancer, osteogenesis, and neural development. Commercial WNT3A antibodies often undergo rigorous validation for sensitivity and cross-reactivity, ensuring reliability in both in vitro and in vivo studies. Their applications extend to drug discovery, particularly in targeting Wnt-driven malignancies and regenerative medicine. Researchers also utilize them to validate CRISPR/Wnt pathway models or assess therapeutic inhibition efficacy.
