IL1B Protein (Native, Human)

• Abbreviation :

  IL1B

• Synonyms :

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

• Host :

  E. coli

• Tag :

  Native

• Endotoxin :

  < 5 EU per mg of the protein as determined by the LAL method.

• Purity :

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

• Bioactivity :

  1.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. 2.Recombinant Human IL1R1 Protein, hFc Tag (Cat. No. 10126-H02H) captured on Protein A chip, can bind Recombinant Human IL-1 beta Protein (Cat. No. 10139-HNAE) with an affinity constant of 0.942 nM as determined in an SPR assay (Biacore T200) (Routinely tested) . 3.Recombinant Human IL1R2 Protein, hFc Tag (Cat. No. 10111-H02H) captured on Protein A chip, can bind Recombinant Human IL-1 beta Protein (Cat. No. 10139-HNAE) with an affinity constant of 2.008 nM as determined in an SPR assay (Biacore T200) (Routinely tested) .
