Description
Noggin is a secreted homodimeric glycoprotein that is an antagonist of bone morphogenetic proteins (BMPs), Noggin antagonizes the biological activity of BMP by blocking the binding of BMP to type I and II receptors. Noggin shows a high affinity to BMP4 but a low affinity to BMP7. During embryogenesis, Noggin antagonizes specific BMPs at defined times, for example, during neural tube, somite and cardiomyocyte growth and patterning. During bone development, Noggin prevents chondrocytes from proliferating so as to allow normal joint formation. During culture of human embryonic stem cells (hESC) or neural stem cells under certain conditions, addition of Noggin to antagonize BMP activity may allow stem cells to proliferate while maintaining their undifferentiated state, or alternatively, to differentiate into dopaminergic neurons. Noggin is expressed in defined areas of the adult central nervous system and peripheral tissues such as lung, skeletal muscle and skin.
Recombinant Human Noggin is expressed by mammalian cells, and is produced with raw materials of pharmaceutical applicable level. The host protein residue, nucleic acid residue and common pathogens are strictly controlled, and the production and quality management procedures of the product comply with GMP regulations to ensure the traceability of the production process and all raw materials.
