BACKGROUND Sonic hedgehog (SHH) 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 and all signal via the same receptors.
Recombinant mouse SHH is a non-glycosylated protein, consisting of 176 amino acids, with a molecular weight of 19.8 kDa. The Cys at position 25 has been substituted with Ile.
Products are for research use only. They are not intended for human, animal, or diagnostic applications.
Cat. No.:
RP2055
Alternative Name:
Shh, HHG-1
Source:
E. coli
Physical Appearance:
Sterile Filtered white lyophilized (freeze-dried) powder.
Formulation:
Recombinant mouse SHH is lyophilized from 10 mM sodium phosphophate buffer, pH 7.5.
Stability:
Lyophilized product is very stable at -20°C. Reconstituted material should be aliquoted and frozen at -20°C. It is recommended that a carrier protein (0.1% HSA or BSA) is added for long term storage.
Reconstitution:
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 0.1 mg/ml, which can be further diluted into other aqueous solutions.
Protein Content and Purity determined by:
UV spectroscopy at 280 nm.
RP-HPLC calibrated against a known standard.
Quantitation against a known standard via reducing and non-reducing SDS-PAGE gels.
Endotoxin Level:
Endotoxin level, as measured by LAL analysis, is <0.01ng/ug or <0.1EU/ug.
Biological Activity:
The activity is measured by the dose-dependent induction of alkaline phosphatase production by C3H/10T1/2 fibroblasts and is typically 0.6-3 ug/ml.
