Stability and Reconstitution

Stability and Storage Lyophilized proteins are stable for 1 year from the date of receipt if stored between (-20°C) and (-80°C). Upon reconstitution we recommend that the solution can be stored at (4°C) for short term or at (-20°C) to (-80°C) for long term. Repeated freeze thaw cycles should be avoided with reconstituted products.
Reconstitution Briefly centrifuge the vial before opening. It is recommended to reconstitute the protein to ≤100μg/mL in sterile 1x PBS pH 7.4 containing 0.1% endotoxin-free recombinant human serum albumin (HSA).


Wnt3A is a member of the Wnt family that consists of structurally linked genes that encode secreted signalling proteins. This protein is associated with oncogenesis and also regulation of cell fate and patterning during embryogenesis. It plays a key role in maintaining the integrity of embryonic and adult tissues. The post-translational glycosylation and acylation of Wnt are essential for their efficient secretion and biological functions (PMID: 8244403; 11834740)
