Noggin 蛋白, Human (CHO)

Noggin Protein, Human (CHO) is an antagonist of bone morphogenetic proteins (BMPs), binds with high affinity to hBMP-4, and with lower affinity to hBMP-7; Noggin Protein is essential for proper skeletal development.

Human Noggin protein has 205 amino acids (residues 28-232) after removal of its signal sequence (residues 1-27) and is secreted as a glycosylated, covalently linked homodimer, binds with high affinity to hBMP-4, and with lower affinity to hBMP-7 and acts as an antagonist of bone morphogenetic proteins (BMPs)^[1]. Noggin is essential for proper skeletal development; excess BMP activity in the Noggin null mutant results in excess cartilage and failure to initiate joint formation^[2].

The ED₅₀ is <2.5 ng/mL as measured by ATDC5 cells.

29-31 kDa

Lyophilized powder.

Lyophilized after extensive dialysis against PBS.

<0.2 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O or PBS.

Stored at -20°C. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer. It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
