Noggin, Active, Recombinant, Human (NOG)

Noggin is a 232aa containing secreted protein belonging to the noggin family. Cartilage morphogenesis and joint formation are some of the functions of Noggin. It also acts as an inhibitor of bone morphogenetic proteins (BMP) signaling which is required for growth and patterning of the neural tube and somite. Defects in NOG are a cause of symphalangism proximal syndrome (SYM1), multiple synostoses syndrome 1 (SYNS1), tarsal-carpal coalition syndrome (TCC) and stapes ankylosis with broad thumb and toes brachydactyly type B2 (BDB2). It shows a restricted expression in few brain parts and uterus. Source: Recombinant corresponding to aa28-232 from Human Noggin expressed in Freestyle 293F cells. Molecular Weight: ~28kD, Endotoxin: ~1EU/ug (LAL) , Biological Activity:, Measured by Noggin's ability to inhibit BMP-4-induced alkaline phosphatase production by C2C12 mouse myoblast cells. The ED50 is <20ng/ml in the presence of 30ng/ml of human BMP-4. Storage and Stability: Lyophilized powder may be stored at -20°C. Stable for 12 months at -20°C. Reconstitute with sterile buffer or ddH2O. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Reconstituted product is stable for 6 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
