IL11 Protein LS-G161 is Recombinant Human IL11 in E. coli It is biologically active and is low in endotoxin Less than 0.1 ng/µg of protein (less than 1EU/µg)..
Predicted Molecular Weight
Greater than 98% by SDS-PAGE and HPLC
The ED50 as determined by the dose-dependent stimulation of the proliferation of murine T11 cells is <=2.0 ng/ml, corresponding to a specific activity of >=5 x 10^5 units/mg.
Less than 0.1 ng/µg of protein (less than 1EU/µg).
Sterile filtered, lyophilized with no additives.
Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.5-1.0 mg/ml. Please Note: This solution is slow to dissolve. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.
If lyophilized, can be stored for 1 month at room temperature, 6 months at 4°C, or through the expiration date at -20°C to -80°C. Once reconstituted per the supplied instructions, can be stored for 3 months at -20°C to -80°C, or for 1 week at 2°C to 8°C. Avoid freeze-thaw cycles.
