Recombinant mature form of human IL1RA isoform1 (NP_776214.1) (Arg 26-Glu 177) was expressed.
Predicted N Terminal:
Lyophilized from sterile PBS, pH 7.4, 5%~8% trehalose and mannitol.
1. Measured by its binding ability in a functional ELISA. Immobilized human IL1RA at 10 μg/ml (100 μl/well) can bind human IL1R2-Fc, The EC50 of human IL1R2-Fc is 0.04-0.1 μg/mL.2. Measured by its binding ability in a functional ELISA. Immobilized human
The recombinant human IL1RA consists of 153 amino acids and predicts a molecular mass of 17.3 kDa which is also estimated by SDS-PAGE.
< 1.0 EU per μg of the protein as determined by the LAL method.
>97 % as determined by SDS-PAGE.
Samples are stable for up to twelve months from date of receipt at -70ºC.
Store it under sterile conditions at -20ºC~-70ºC. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
It is recommended that sterile water be added to the vial to prepare a stock solution of 0.25 ug/ul. Centrifuge the vial at 4ºC before opening to recover the entire contents.
