Recombinant Mouse Noggin

Cat. No.: Nog -954M
Product Overview: Recombinant mouse Noggin produced inE.Coliis a 46.4 kDa disulfide-linked homodimer consisting of two 206 amino acid polypeptide chains.
Description: Noggin belongs to a group of diffusible proteins which bind to ligands of the TGF-β family and regulate their activity by inhibiting their access to signaling receptors. The interplay between TGF-β ligands and their natural antagonists has major biological significance during development processes, in which cellular response can vary considerably depending upon the local concentration of the signaling molecule. Noggin was originally identified as a BMP-4 antagonist whose action is critical for proper formation of the head and other dorsal structures. Consequently, Noggin has been shown to modulate the activities of other BMPs including BMP-2,-7,-13, and -14. Targeted deletion of Noggin in mice results in prenatal death and recessive phenotype displaying a severely malformed skeletal system. Conversely, transgenic mice over-expressing Noggin in mature osteoblasts display impaired osteoblastic differentiation, reduced bone formation, and severe osteoporosis.
Source: E.Coli.
Purity: > 95% by SDS-PAGE.
Endotoxin Level: < 0.1 ng per μg of NOGGIN.
Stabilizer: None.
Formulation: Lyophilized.
Biological Activity: Determined by its ability to inhibit 5.0 ng/ml of BMP-4 induced alkaline phosphatase production by ATDC chondrogenic cells. The expected ED50for this effect is 1.0-2.0 ng/ml of Noggin.
Stability: The lyophilized protein is stable for at least 2 years from date of receipt at -20°C. Reconstituted NOGGIN is stable for at least 3 months when stored in working aliquots with a carrier protein at -20°C. Avoid repeated freeze-thaw cycles.
