|
活性(Activity) |
ELISA Data: Immobilized Rat GDF-15, His Tag at 2μg/ml (100μl/well) on the plate. Dose response curve for Human GFRAL, hFc Tag with the EC50 of 17.2ng/ml determined by ELISA .Immobilized Rat GDF15, His Tag at 5μg/ml (100μl/Well) on the plate. Dose response curve for Biotinylated Mouse GFRAL, His Tag with the EC50 of 0.95μg/ml determined by ELISA. |
|
制剂(Formulation) |
Lyophilized from 0.22μm filtered solution in 50mM HAc (pH 2.9). Normally 8% trehalose is added as protectant before lyophilization. |
|
重构方法(Reconstitution) |
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in 50mM HAc (pH 2.9). |
