Biotin |
| Purity |
> 95% as determined by Bis-Tris PAGE |
| Endotoxin Level |
Less than 1 EU per μg by the LAL method. |
| Biological Activity |
Measured by its binding ability in a functional ELISA. Immobilized Human GFRAL, hFc Tag at 5μg/ml (100 μl/Well) on the plate can bind GDF15[Biotin], His & Avi, Human. Test result was comparable to standard batch. |
| Expression System |
E.coli |
| Theoretical Molecular Weight |
15.19 kDa |
| Apparent Molecular Weight |
The protein has a predicted MW of 15.19 kDa same as Bis-Tris PAGE result. |
| Formulation |
Lyophilized from 0.22 μm filtered solution in 50 mM HAc (pH 2.9). |
| Reconstitution |
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in 50 mM HAc (pH 2.9). |
| Storage & Stability |
Upon receiving, the product remains stable up to 6 months at -20 °C or below. Upon reconstitution, the product should be stable for 3 months at -80 °C. Avoid repeated freeze-thaw cycles. |
| Target Background |
Growth Differentiation Factor 15 (GDF15), also known as NSAID activated gene-1 (NAG-1), is associated with a large number of biological processes and diseases, including cancer and obesity. GDF15 is synthesized as pro-GDF15, is dimerized, and is cleaved and secreted into the circulation as a mature dimer GDF15. |
