Formulation
Lyophilized from 0.22 um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water.
Stability And Storage
Reconstituted protein stable at -80°C for 12 months, 4°C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
Human Betacellulin on Bis-Tris PAGE under reduced condition. The purity is greater than 95%.
Measured in a cell proliferation assay using Balb/3T3 mouse embryonic fibroblast cells. The ED50-for this effect is 0.10-1.50 ng/ml (QC Test).
The purity of Human Betacellulin is greater than 95% as determined by SEC-HPLC.
