分子别名（Synonym）:IL-1,IL-1 beta,IL-1B,IL1-BETA,IL1F2

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 IL1β consisting of 154 amino acids migrates with an apparent molecular mass of 17 kDa as estimated in SDS-PAGE under reducing conditions.

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 recombinant human IL1B at 2 μg/mL (100μl/well) can bind recombinant human IL1R2 with a linear range of 6.25-400 ng/ml.

表达区间（Protein Construction）：A DNA sequence encoding the mature form of human IL1β (NP_000567.1) (Ala 117-Ser 269) 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.
