Description

Sonic Hedgehog (Shh) is expressed in embryonic tissues that are critical for the patterning of the developing central nervous system, somite, and limb. Shh-N is highly conserved, sharing >98% aa identity between mouse, human, rat, canine, porcine, and chicken Shh-N. The Hedgehog (Hh) family of secreted proteins plays an essential role in metazoan development, and defects in the Hh pathway lead to congenital abnormalities such as holoprosencephaly and certain forms of cancer. Shh is the most widely expressed of the many ligands, and much of what is known about vertebrate Hh signaling stems from studies on Shh. Though similar in many ways to the DrosophilaHh pathway, several features of vertebrate Hh signaling make it unique.

Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Purity

> 98% by SDS-PAGE and HPLC analyses.

Biological Activity

The ED50 as determined by inducing alkaline phosphatase production of murine C3H/10T1/2 cells is less than 1 μg/mL, corresponding to a specific activity of > 1.0 × 103 IU/mg. Fully biologically active when compared to standard.

Endotoxin

< 1.0 EU per 1μg of the protein by the LAL method.

Formulation

Lyophilized from a 0.2 μm filtered concentrated solution in 20 mM PB, pH 7.4, 150 mM NaCl.

Reconstitution

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20°C. Further dilutions should be made in appropriate buffered solutions.
