  IL1B

• Synonyms :

  IL-1, IL-1B, IL1-BETA, IL1beta, IL1F2

• Host :

  E. coli

• Tag :

  Native

• Endotoxin :

  < 10 EU per mg of the protein.

• Purity :

  ≥ 95 % as determined by SDS-PAGE. ≥ 95 % as determined by SEC-HPLC.

• Bioactivity :

  Measured by its ability to induce Interferon gamma secretion by human natural killer lymphoma NK-92 cells. The ED50 for this effect is typically 0.2-2 ng/ml. The specific activity of recombinant human IL-1 beta is >60,000 IU/μg, which is calibrated against the human IL-1 beta WHO International Standard (NIBSC code: 86/680) .

• Function :

  Ala117-Ser269

• Molecular Weight :

  The recombinant human IL1B consists of 154 amino acids and predicts a molecular mass of 17.5 kDa

• Species :

  Human
