Mouse WNT8A, Tag Free is widely used in developmental biology research, particularly in studies involving embryogenesis and cell fate determination. It plays a critical role in activating the Wnt/β-catenin signaling pathway, making it valuable for investigating axis patterning, mesoderm specification, and neural crest development in vertebrate models. Due to its tag-free nature, it is ideal for structural studies, protein-protein interaction assays, and functional experiments where tags could interfere with receptor binding or signaling activity. It is also employed in stem cell research to modulate differentiation pathways, especially in models of early embryonic development and tissue regeneration. Its application extends to in vitro systems such as cell culture and organoid models to study signaling dynamics without the influence of purification tags.
