Recombinant Human SHH Protein
|Sonic Hedgehog||Recombinant Human Sonic Hedgehog is a member of a small group of secreted proteins that are essential for development in both vertebrates and invertebrates. Three mammalian hedgehog genes (sonic, desert, Indian) share about 60% homology. The Cys at position 25 has been substituted with Ile. Human SHH is a non-glycosylated polypeptide.||Human recombinant Sonic Hedgehog is biologically active as compared to a standard. The ED50, measured by the dose-dependent induction of alkaline phosphatase production by C3H/10T1/2 fibroblasts, is 750ng/ml.|

Sterile Filtered white lyophilized (freeze-dried) powder.
Lyophilized from 50 mM KP, 300 mM KCl, pH 7.5.
Centrifuge vial before opening. When reconstituting the product, gently pipet and wash down the sides of the vial to ensure full recovery of the protein into solution. It is recommended to reconstitute the lyophilized product with sterile water at a concentration of 0.1mg/ml, which can be further diluted into other aqueous solutions.
Lyophilized product is very stable at -20°C. Reconstituted material should be aliquoted and frozen at -20°C. It is recommended to add a carrier protein (0.1% HSA or BSA) for long term storage.
Endotoxin level as measured by LAL is <0.01ng/ug or <0.1EU/ug.
