Interleukin 1 alpha (IL-1ϫ) also known as hematopoietin 1 is a cytokine of the interleukin 1 family that in humans is encoded by the IL1A gene. IL-1ϫ is produced mainly by activated macrophages, as well as neutrophils, epithelial cells, and endothelial cells. It possesses metabolic, physiological, haematopoietic activities, and plays one of the central roles in the regulation of the immune responses. It binds to the interleukin-1 receptor. It is on the pathway that activates tumor necrosis factor-alpha.

Measure by its ability to induce D10.G4.1 cells proliferation. The ED50 for this effect is <5 pg/mL. The specific activity of recombinant mouse IL-1 alpha is > 2 x 108 IU/mg.
Endotoxin level:<0.1 EU per 1 ug of the protein by the LAL method.
Calculated Molecular Weight:18.93 kDa
Formulation:The protein was lyophilized from a solution containing 1X PBS, pH 7.4.
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.
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.
