| Formulation |
Lyophilized from a 0.2um filtered solution in PBS. |
| Solubility |
It is recommended to reconstitute the lyophilized TSG in sterile 18M-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions. |
| Purity |
Greater than 95.0% as determined by SDS-PAGE. |
| 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. |
| Protein Background |
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. |
| Expression host |
CHO. |
| Synonyms |
Twisted Gastrulation BMP Signaling Modulator 1, TSG, Twisted Gastrulation Homolog 1 (Drosophila), Twisted Gastrulation Protein Homolog 1, Twisted Gastrulation Homolog 1, TWSG1. |
| Reagent Appearance |
Sterile Filtered White lyophilized (freeze-dried) powder. |
| 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. |
