Small and Specialty Supplier Partner
Small and/or specialty supplier based on Federal laws and SBA requirements.
Learn More

Recombinant human Wnt3a surrogate protein (HEK293, Fc) is a water-soluble, Fc-fused Wnt agonist engineered to provide Fzd isoform-selective activation of canonical Wnt signaling. Expressed in HEK293 cells to preserve human-like post-translational modifications, the surrogate serves as a defined, consistent Wnt source for organoid culture, stem cell maintenance, and in vitro signaling assays.

• Water-soluble Fc-fused surrogate for simplified handling and solubility
• Fzd isoform-selective activation enables tissue-relevant Wnt signaling
• Expressed in HEK293 cells to support human-like post-translational modifications
• Supports organoid expansion and stem cell maintenance in culture
• Available in defined microgram quantities for assay flexibility
• Reduces variability compared with lipidated Wnt or conditioned media
