The WNT2 antibody is a crucial tool for studying the WNT2 protein, a member of the Wnt family of secreted signaling glycoproteins. Wnt proteins play pivotal roles in embryonic development, tissue homeostasis, and cell proliferation/differentiation via evolutionarily conserved pathways, primarily the canonical Wnt/β-catenin signaling. WNT2. encoded by the WNT2 gene, binds to Frizzled receptors and co-receptors (e.g., LRP5/6), activating downstream targets like β-catenin to regulate gene expression. Dysregulation of WNT2 is implicated in cancers (e.g., lung, colorectal), fibrosis, and developmental disorders, making it a research focus in oncology and regenerative medicine.
WNT2 antibodies are designed to detect and quantify WNT2 expression in various experimental models. They are widely used in techniques like Western blotting, immunohistochemistry (IHC), immunofluorescence (IF), and ELISA to study WNT2's localization, expression levels, and interactions. Due to WNT2's post-translational lipid modifications (e.g., palmitoylation), antibody specificity is critical, requiring validation in knockout controls. Some antibodies block WNT2 function, aiding mechanistic studies. Commercial WNT2 antibodies vary in clonality (monoclonal/polyclonal), species reactivity (human, mouse, rat), and applications, necessitating careful selection based on experimental needs. Their utility extends to exploring WNT2's role in disease pathways and therapeutic targeting.
