Analysis Note

The activity was determined by dose dependent Alkaline Phosphatase production in MC3T3 E1 mouse preosteoblast cells and stabilization of beta catenin in mouse L929 cells.

General description

Wnt3A is a member of the Wnt gene family that consists of structurally linked genes that encode secreted signaling proteins.


It is recommended to reconstitute the protein to ≤100μg/mL in sterile 1X PBS containing 0.1% endotoxin-free HSA.

Physical form

Lyophilized from a 0.2 μm filtered solution containing 0.064 mg/mL protein in 1X PBS pH 7.4 + 500mM NaCl + 1% CHAPS.

Storage and Stability

Upon reconstitution, the cytokine can be stored at 4°C for short term or at -20°C to -80°C in aliquots for long term. Avoid repeated freeze-thaw cycles.
