Structural Info | |||||
Formulation | Lyophilized in sterile filtered solution of PBS. | ||||
Reconstitution | Before reconstitution, a brief spin is recommend todrive down any material dislodged from the bottom of the tube. The lyophilized protein should be reconstitutedin sterile H2O to a desired concentration. | ||||
Stability | The lyophilized protein is stable for at least oneyear if stored at -80°C. Reconstituted protein is stable for at least four weeks at 4 °C,but should be stored in aliquots at -80 °C for longer term. Avoidrepeated freeze and thaw. | ||||
Purity | Greater than 90% as determined by SDS-PAGE analysis | ||||
Biological Activity | The activity was determined by using a TCF reporter gene assay in cultured human cells.The IC50 ranges from 200 - 1000 ng/ml in the inhibition of 100 ng/mL WNT-3a activity.Activity in other assays | ||||
