Description

Extensive quality control produces industry leading bioactivity and lot-to-lot consistency that instills confidence in results and ensures reproducibility. Applications: Bioactivity

Measured in a cell proliferation assay using D10.G4.1 mouse helper T cells. Symons, J.A. et al. (1987) in Lymphokines and Interferons, a Practical Approach. Clemens, M.J. et al. (eds): IRL Press. 272. The ED50 for this effect is <12 pg/mL. The specific activity of recombinant human IL-1 beta is approximately 1.4 x 105 IU/μg, which is calibrated against recombinant human IL-1 beta WHO International Standard (NIBSC code: 86/680). Specific activity is for reference purposes only and is not routinely tested.
