High-Purity, Stabilized Wnt3a for Reliable Organoid and Stem Cell Culture

Recombinant Afamin/Wnt3a is a stabilized, bioactive complex of mouse Wnt3a and human Afamin, designed to overcome the solubility and stability limitations of conventional Wnt3a proteins in serum-free systems. This ready-to-use recombinant formulation enables consistent Wnt pathway activation for demanding applications in organoid culture, stem cell maintenance, and Wnt signaling research.

Key Benefits

Enhanced Solubility & Stability – Afamin prevents Wnt3a aggregation, preserving bioactivity in defined media
Functionally Active & High Purity – 90% pure recombinant protein complex, verified by SDS-PAGE
Ready for Experimental Use – Supplied in Tris-HCl buffer with no need for pre-conditioning or serum
Recombinantly Expressed in CHO-K1 Cells – PA-tagged Wnt3a (~41 kDa) and Myc-tagged Afamin (~70 kDa) for traceability
Flexible for Small-Scale or Pilot Studies – 60 µg total protein (300 µL) in a convenient liquid format

Applications

Organoid generation from digestive tissues
Long-term Lgr5+ stem cell culture
Canonical Wnt signaling pathway studies in vitro

Storage & Handling

Store at –20°C or below. To maintain activity after dilution, use PBS with 0.04% HSA or BSA and avoid repeated freeze–thaw cycles.

Note: Some applications may be subject to third-party patents. Please consult your institution’s IP office for guidance.
