- Product name
Human IL-1 alpha protein
Amino acid sequence derived from the processed form of human IL1α (NP_000566.3) (Ser 113-Ala 271) was expressed and purified.
Measured in a cell proliferation assay using D10.G4.1 mouse helper T cells. The ED50 for this effect is typically 0.2-1 ng/mL .
- Protein length
The recombinant human IL1α consists of 159 amino acids and has a predicted molecular mass of 18 kDa. As a result of glycosylation, the apparent molecular mass of rhIL1α is approximately 22 kDa in SDS-PAGE under reducing conditions.
- Preparation method
> 95 % as determined by SDS-PAGE
Lyophilized from sterile 50mM Tris, 100mM NaCl, pH 8.0
- Molecular weight
- Usage notes
Always centrifuge tubes before opening. It is recommended to reconstitute the lyophilized Human IL-1 alpha protein in sterile ddH2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
- Storage instructions
Lyophilized Human IL-1 alpha protein product should be stored desiccated below -18°C. Upon reconstitution, the protein should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
The product is shipped at ambient temperature.

IL-1 alpha is a member of the interleukin 1 cytokine family. Cytokines are proteinaceous signaling compounds that are major mediators of the immune response. They control many different cellular functions including proliferation, differentiation and cell survival/apoptosis but are also involved in several pathophysiological processes including viral infections and autoimmune diseases. Cytokines are synthesized under various stimuli by a variety of cells of both the innate (monocytes, macrophages, dendritic cells) and adaptive (T- and B-cells) immune systems. Cytokines can be classified into two groups: pro- and anti-inflammatory. Pro-inflammatory cytokines, including IFNgamma, IL-1, IL-6 and TNF-alpha, are predominantly derived from the innate immune cells and Th1 cells. Anti-inflammatory cytokines, including IL-10, IL-4, IL-13 and IL-5, are synthesized from Th2 immune cells. IL-1 alpha is a pleiotropic cytokine involved in various immune responses, inflammatory processes, and hematopoiesis. It is produced by monocytes and macrophages as a proprotein, which is proteolytically processed and released in response to cell injury, and thus induces apoptosis. IL-1 alpha stimulates thymocyte proliferation by inducing IL-2 release, B-cell maturation and proliferation, and fibroblast growth factor activity.
