ActoFactor™ Recombinant Human Sonic hedgehog

  • Specification
Cat.No.
CSC-CTK0510
Description
Members of the Hedgehog (Hh) family are highly conserved proteins which are widely represented throughout the animal kingdom. The three known mammalian Hh proteins, Sonic (Shh), Desert (Dhh) and Indian (Ihh) are structurally related and share a high degree of amino- acid sequence identity (e.g., Shh and Ihh are 93% identical). The biologically active form of Hh molecules is obtained by autocatalytic cleavage of their precursor proteins and corresponds to approximately the N-terminal one half of the precursor molecule. Although Hh proteins have unique expression patterns and distinct biological roles within their respective regions of secretion, they use the same signaling pathway and can substitute for each other in experimental systems. 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 natural occurring chemically modified Cys residue.
Species
Human
Product Overview
Human SHH expressed in E.coli
Molecular Mass
20 kDa
Size
CAT# CSC-CTK0510-25 (25 μg); CAT# CSC-CTK0510-125 (125 μg)
Expression System
E.coli
Purity
Greater than 98% as determined by SDS-PAGE and RP-HPLC analysis.
Activity
Determined by its ability to induce alkaline phosphatase production by C3H/10T1/2 (CCL-226) cells. The expected ED50 for this effect is 0.8-1.0 μg/ml.
Endotoxin Level
Less than 1 EU/μg.
Formulation
Sterile-filtered through a 0.2 micron filter. Lyophilized from a protein solution with no additives.
Reconstitution
Please centrifuge product briefly before opening vial. The lyophilized protein should be reconstituted in sterile, ultrapure water or aqueous buffers to a concentration of 0.1- 1.0 mg mg/ml. This solution can then be diluted into other aqueous buffers and stored at -20°C for future use.
Storage & Stability
The lyophilized protein, though stable at room temperature for up to 3 weeks, is best stored desiccated at -20°C. Reconstituted protein should be used immediately or stored long-term in undiluted working aliquots at -20°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid repeated freeze-thaw cycles.
