|GREM1, Cktsf1b1, Drm|
|A DNA sequence encoding the mouse GREM1 (O70326) (Met1-Asp184) was fused with a polyhistidine tag at the C-terminus.|
|In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.|
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
|> 97 % as determined by SDS-PAGE|
|Measured by its ability to inhibit recombinant human BMP4 induced alkaline phosphatase production by MC3T3-E1 cells.|
The ED50 for this effect is typically 1-7 μg/mL in the presence of 50 ng/mL of recombinant human BMP4.
|< 1.0 EU per μg of the protein as determined by the LAL method|
|Samples are stable for up to twelve months from date of receipt at -70℃|
|The recombinant mouse GREM1 consists of 171 amino acids and has a calculated molecular mass of 19.7 kDa. The recombinant protein migrates as an approximately 25 kDa band in SDS-PAGE under reducing conditions.|
|Lyophilized from sterile 20mM Tris, 500mM NaCl, pH 7.4, 10% gly, 0.5mM EDTA, 3mM DTT|
1. Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
2. Please contact us for any concerns or special requirements.
|Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.|
|A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.|
GREM1 belongs to the DAN family. It contains 1 CTCK (C-terminal cystine knot-like) domain. GREM1 is a cysteine knot-secreted protein and acts as an inhibitor in the TGF beta signaling pathway. It inhibits BMP-2, -4, and -7. Inhibition by grem 1 of BMPs in mice allow the expression of fibroblast growth factors (FGFs) 4 and 8 and Sonic hedgehog (SHH) which are necessary for proper limb development. It interacts with SLIT1 and SLIT2 in a glycosylation-dependent manner. As a cytokine, GREM1 may play an important role during carcinogenesis and metanephric kidney organogenesis, as a BMP antagonist required for early limb outgrowth and patterning in maintaining the FGF4-SHH feedback loop. It down-regulates the BMP4 signaling in a dose-dependent manner. It also acts as inhibitor of monocyte chemotaxis. GREM1 is highly expressed in small intestine, fetal brain and colon.
