Background

Noggin is a secreted glycoprotein predominantly expressed by the dorsal mesoderm during embryogenesis that inhibits TGF-β signal transduction by binding to TGF-β family ligands and preventing them from binding to their corresponding receptors. Noggin is expressed in condensing cartilage and immature chondrocytes.1 Noggin plays a key role in neural induction by inhibiting BMP4, along with other TGF-β signaling inhibitors such as chordin and follistatin. Noggin plays a crucial role in bone development, joint formation, and neural tube fusion.

Protein Details

Purity
>95% by SDS Page and HPLC
Endotoxin Level
<0.1 EU/µg as determined by the LAL method
Biological Activity
The biological activity of Human Noggin was determined by its ability to inhibit 5.0 ng/ml of BMP-4 induced alkaline phosphatase production by ATDC-5 chondrogenic cells. The expected ED50 for this effect is 0.05-0.08 µg/ml of NOGGIN.
