Human Noggin, Fc tag, HEK293
Noggin is a bioactive protein intended for use in cell culture applications. Noggin protein which bind to ligands of the TGF-β family and regulate their activity by inhibiting their access to signaling receptors. Noggin was originally identified as a BMP-4 antagonist whose action is critical for proper formation of the head and other dorsal structures.
Sequence:

UnitProt ID:
Q13253
Species of Origin:
Human
Expression System:
HEK293 cell
Affinity Tag:
Endotoxin Test:
<0.1 EU per 1 μg of the protein by the LAL method.
Activity:
Measure by its ability to inhibit BMP-4-induced alkaline phosphatase production by ATDC5 cells.
