- BACKGROUND
Description | Twisted Gastrulation Protein (TSG) is a secreted BMP binding protein structurally related to the BMP antagonists Chordin and Noggin. TSG can inhibit BMP activity by binding directly to BMP proteins, and can act either as a BMP4 agonist or antagonist (depending on the specific biochemical environment) by binding to the BMP4/Chordin complex. Recombinant human TSG is a 198 amino acid 22.2 kDa protein containing the BMP/TGFβ binding portion of the full length TSG protein. |
---|---|
BiologicalActivity | Determined by its ability to neutralize BMP-6 induced alkaline phosphatase production by ATDC chondrogenic cells. The expected ED50 for this effect is < 2.0 μg/ml of TSG. |
Authenticity | Verified by N-terminal and Mass Spectrometry analyses (when applicable). |
Endotoxin | Endotoxin level is <0.1 ng/ µg of protein (<1EU/ µg). |
Protein Content | Verified by UV Spectroscopy and/or SDS-PAGE gel. |
Storage | -20°C |
Precautions | Recombinant Human TSG is for research use only and not for use in diagnostic or therapeutic procedures. |
