Purity |
> 95% as determined by BisTris PAGE > 95% as determined by HPLC |
Endotoxin Level |
Less than 1EU per μg by the LAL method. |
Biological Activity |
Measured by its binding ability in a functional ELISA. Immobilized IL-11, His, Human at 2μg/ml (100 μl/Well) on the plate can bind Human IL11 R alpha, hFc Tag. Test result was comparable to standard batch. |
Expression System |
HEK293 |
Theoretical Molecular Weight |
20.24 kDa |
Apparent Molecular Weight |
Due to glycosylation, the protein migrates to 21-25 kDa based on Bis-Tris PAGE result. |
Formulation |
Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). |
Reconstitution |
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. |
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 |
Abstract Interleukin-11 (IL-11) is a pleiotropic cytokine that belongs to gp130 family. IL-11 and its receptor, IL-11Ra, are expressed in human cancers, human cancer cells expressed a functional IL-11Ra subunit, which triggered signal transduction either by exogenous recombinant human IL-11 or by autocrine production of IL-11 in cells cultured under hypoxic conditions. |
