Purity > 95% as determined by Bis­Tris PAGE
> 95% as determined by HPLC
Endotoxin Level Less than 0.1EU per μg by the LAL method.
Biological Activity Measured by its binding ability in a functional ELISA. Immobilized LIF, Human at 2μg/ml (100μl/well) on the plate can bind Human LIF R, His Tag. Test result was comparable to standard batch.
Expression System E.coli
Theoretical Molecular Weight 19.86 kDa
Apparent Molecular Weight The protein has a predicted MW of 19.86 kDa same as 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.
