分子别名（Synonym）:DIRA,ICIL-1RA,IL-1ra,IL-1ra3,IL-1RN,IL1F3,IL1RA,IRAP,MVCD4

种属（Species）：Human

表达系统（Expressed Host）：E. coli

产品状态（Buffer）：Lyophilized from sterile PBS, pH 7.4

分子量（Molecule Mass）：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.

内毒素（Endotoxin）：＜1.0 EU per μg by the LAL method.

生物活性(Activity)：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 (Cat:H1335-202H), The EC50 of human IL1R2-Fc (Cat:H1335-202H) is 0.04-0.1 μg/mL.

表达区间（Protein Construction）：A DNA sequence encoding the mature form of human IL1RA isoform1 (NP_776214.1) (Arg 26-Glu 177) was expressed.

存储条件（Storage）： For long term storage, the product should be stored at lyophilized state at -20℃ or lower.Please avoid repeated freeze-thaw cycles. No activity loss is observed after storage at:4-8℃ for 12 months in lyophilized state;-70℃ for 3 months under sterile conditions after reconstitution.

运输条件： In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
