Application

The sonic hedgehog protein is used in neuronal induction medium as a supplement.

Sonic Hedgehog human has been used:To study its role in liver cancer stem cell activity. For neuronal differentiation.For cholinergic-like neurons (ChLNs) differentiation.

Biochem/physiol Actions

The SHH (sonic hedgehog) gene encodes a soluble signaling protein that functions in the patterning of cell differentiation in the neural tube and limb bud. It has also been implicated in several processes, such as developing nervous system, including midbrain and ventral forebrain neuronal differentiation and neuronal precursor proliferation. In adults, it regulates progenitor function and proliferation. Mutations in this gene have been associated with holoprosencephaly, a developmental defect of the forebrain and midface.

General description

The sonic hedgehog protein is encoded by the SHH gene that is mapped to human chromosome 7q36. It is homologous to the Drosophila segment polarity gene hedgehog. The encoded protein is a 45kDa precursor protein that is auto-cleaved to form SSH-N (an amino-terminal 20kDa product) and SSH-C (carboxy-terminal product). SSH-N is found to be cell-associated, while SSH-C diffuses freely. Recombinant E. coli derived Human Sonic HedgeHog is a 20.0 kDa protein consisting of 176 amino acid residues, including an N-terminal Ile-Val-Ile sequence substituted for the naturally occurring chemically modified Cys residue.

Physical form

Lyophilized with no additives.

Reconstitution

Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1- 1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.
