Product Information
Description: Interleukin 1 (IL-1) is a peptide with a molecular mass of 17 kd and two isoforms, IL-1α and IL-1β. IL-1ɑ consists of 159 amino acids. Measured by its ability to induce interferon γ secretion from human natural killer lymphoma NK-92 cells, the ED50 of this effect is ≤100 ng/mL.
   
Stability and Solubility Advice: Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide.
We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details.
