Product Tag	No Tag
Express System	HEK293
Purity	> 95% as determined by Tris-Bis PAGE;> 95% as determined by HPLC
Endotoxin	Less than 1EU per ug by the LAL method.

Form	Lyophilized
Shipping	Shipped at ambient temperature.
Formulation	Lyophilized from 0.22um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution	Centrifuge the tube before opening. Reconstituting to a concentration more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water.
Stability And Storage	Reconstituted protein stable at -80°C for 12 months, 4°C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles.

	Immobilized Human LIF at 2ug/ml (100ul/Well) on the plate. Dose response curve for Human LIF R, hFc Tag with the EC50 of 55.9ng/ml determined by ELISA.
	The purity of Human LIF is greater than 95% as determined by SEC-HPLC.
