Description
Wnt-3a is a secreted glycoprotein that activates canonical Wnt/β-catenin signaling, a pathway central to stem cell self-renewal, tissue patterning, and oncogenesis. This recombinant protein, spanning the full mature sequence (aa 19–352) and produced in mammalian cells to preserve native glycosylation, induces Topflash reporter activity in CHO-K1 cells with an ED50 below 30 ng/ml, demonstrating potent receptor engagement suitable for stem cell maintenance assays, neuronal and osteogenic differentiation protocols, and mechanistic studies of Wnt pathway activation. The mammalian expression system ensures post-translational modifications essential for receptor binding, supporting use in receptor-ligand competition assays by ELISA or surface plasmon resonance, as well as in tumor biology models where canonical Wnt signaling drives proliferation. Purity exceeding 95% by SDS-PAGE and endotoxin levels at or below 100 EU/mg align with standards expected in cell-based functional assays and antibody characterization workflows.
