Active Recombinant Human IL1B protein(Met1-Ser269), His-tagged

• Cat.No.: IL1B-744H
• Product Overview: Recombinant Human IL1β (NP_000567.1, with mutation Glu 6 Lys) (Met 1-Ser 269) was expressed in E. coli, fused with a polyhistidine tag at the N-terminus.

Specification

• Species: Human
• Source: E.coli
• Tag: His
• Protein Length: Met1-Ser269
• Form: Lyophilized from sterile PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
• Bio-activity: 1. Measured by its binding ability in a functional ELISA. 2. Immobilized human IL1B at 10 μg/mL (100 μl/well) can bind human IL1R1. The EC50 of human IL1R1 is 0.198 μg/mL.
• Molecular Mass: The recombinant pro form of human IL1β consisting of 280 amino acids and has a calculated molecular mass of 32.3 kDa. It migrates as an approximately 34 kDa band in SDS-PAGE under reducing conditions.
• Purity: > 95 % as determined by SDS-PAGE
• Storage: Samples are stable for up to twelve months from date of receipt at -20°C to -80°C. Store it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
• 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.
