Description
Noggin belongs to a group of diffusible proteins which bind to ligands of the TGF-ß family and regulate their activity by inhibiting their access to signaling receptors. The interplay between TGF-ß 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.
M.W.
Approximately 46.4 kDa disulfide-linked homodimer consisting of two 206 amino acid polypeptide chains.
Purity
>95% by SDS-PAGE and HPLC analyses.
Endotoxin Level
Less than 0.2EU/ug of rMuNOGGIN as determined by LAL method.
Specific Activity
Determined by its ability to inhibit 5.0 ng/ml of BMP-4 induced alkaline phosphatase production by ATDC chondrogenic cells. The expected ED50 for this effect is 1.0-2.0 ng/ml of Noggin, corresponding to a specific activity of > 5.0x105 units/mg.
Storage
This lyophilized preparation is stable at 2-8 C, but should be kept at -20 C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8 C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 C to -70 C. Avoid repeated freeze/thaw cycles.
Formulation
Lyophilized from a 0.2um filtered concentrated, solution in 30% acetonitrile, 0.1% TFA.
Reconstitution
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in 10mM HAc to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at <-20C. Further dilutions should be made in appropriate buffered solutions.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Usage
This material is for research, laboratory or further evaluation purposes. NOT FOR HUMAN USE.
