Interleukin 1 beta (IL-1ÉÇ) also known as leukocytic pyrogen, leukocytic endogenous mediator, mononuclear cell factor, lymphocyte activating factor and other names, is a cytokine protein that in humans is encoded by the IL1B gene. There are two genes for interleukin-1 (IL-1): IL-1 alpha and IL-1 beta (this gene). IL-1ض precursor is cleaved by cytosolic caspase 1 (interleukin 1 beta convertase) to form mature IL-1ÉÇ.

Measure by its ability to induce proliferation in D10.G4.1 cells. The ED50 for this effect is <10 pg/mL. The specific activity of recombinant human IL-1 beta is approximately >1.5 x 108 IU/mg. Measure by its ability to induce IL-8 secretion in HT29 cells. The ED50 for this effect is 1.8-5.1 ng/mL.
Endotoxin level: <0.1 EU per 1 ug of the protein by the LAL method.
Calculated Molecular Weight: 18.48 kDa
Formulation: The protein was lyophilized from a solution containing 1X PBS, pH 8.0.
It is recommended to reconstitute the lyophilized protein in sterile H2O to a concentration not less than 100 ug/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.
Shipping: Blue Ice
Stability and Storage:
Lyophilized protein should be stored at -20 degrees Celsius for 1 year. Upon reconstitution, store at 2 degrees Celsius to 8 degrees Celsius for up to 1 week. Further dilute in a buffer containing a carrier protein or stabilizer (e.g. 0.1% BSA, 10%FBS, 5%HSA or 5% trehalose solution), protein aliquots should be stored at -20 degrees Celsius or -80 degrees Celsius for 3-6 months.
SDS-PAGE Image Name: human IL-1 beta
