                                Introduction
                                Twisted gastrulation Protein (TSG) is a secreted, cysteine-rich protein which has a role in dorsal/ventral patterning in Drosophila and Xenopus by regulating BMP signaling. TSG functions as an agonist for BMP signaling by controlling the inhibitory actions of the BMP antagonist, Chordin/Sog, and the cleavage properties of the metalloprotease, xolloid/tolloid. TSG N-terminal domain binds BMP protein directly and displays BMP antagonist activity.
                                Description
                                TWSG1 Human Recombinant (26-223) produced in CHO is a single, glycosylated, polypeptide chain containing 198 amino acids and having a molecular mass ranging from 35-43kDa on SDS-PAGE due to glycosylation.
The TWSG1 is purified by proprietary chromatographic techniques.
                                Source
                                CHO.
                                Physical Appearance
                                Sterile Filtered White lyophilized (freeze-dried) powder.
                                Formulation
                                Lyophilized from a 0.2μm filtered solution in PBS.
                                Solubility
                                It is recommended to reconstitute the lyophilized TSG in sterile 18M-cm H2O not less than 100μg/ml, which can then be further diluted to other aqueous solutions. 
                                Stability
                                Lyophilized TSG although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution TSG should be stored at 4°C between 2-7 days and for future use below -18°C.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
                                Purity
                                Greater than 95.0% as determined by SDS-PAGE.
