Medchemexpress LLC Wnt3a Surrogate Hum 5ug
SDP

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
