Active Recombinant Human IL1B protein, Fc-tagged

• Cat.No.: IL1B-2121H
• Product Overview: Recombinant Human IL1B protein(Ala 117 - Ser 269), fused with Fc tag, was expressed in HEK293.

Specification

• Source: HEK293
• Species: Human
• Tag: Fc
• Form: Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.
• Bio-activity: Immobilized Human IL-1 RII, His Tag at 5 μg/mL (100 μL/well) can bind Human IL-1 beta, Fc Tag with a linear range of 4.9-39 ng/mL.
• Molecular Mass: This protein carries a human IgG1 Fc tag at the N-terminus.The protein has a calculated MW of 43.8 kDa. The protein migrates as 50-55 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
• Protein Length: Ala117-Ser269
• Endotoxin: Less than 1.0 EU per μg by the LAL method.
• Purity: >95% as determined by SDS-PAGE.>90% as determined by SEC-MALS.
• Storage: For long term, the product should be stored at lyophilized state at -20°C or lower.Please protect from light and avoid repeated freeze-thaw cycles.This product is stable after at: -20°C to -70°C for 12 months in lyophilized state; -70°C for 3 months under sterile conditions after reconstitution.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
