Mouse WNT5B, Tag Free is primarily used in research settings to study developmental biology and cellular signaling pathways. It plays a key role in activating non-canonical Wnt signaling, which regulates processes such as cell polarity, migration, and tissue morphogenesis. Researchers use this protein to investigate embryonic development, stem cell differentiation, and tissue regeneration. It is also applied in cancer research, as WNT5B has been linked to tumor progression and metastasis in certain types of cancers. Its tag-free form allows for native-like behavior in assays, making it suitable for protein-protein interaction studies, receptor binding assays, and structural analysis. Additionally, it supports the development and maintenance of specialized cell types in 3D culture systems and organoids.
