Known as | Interleukin-1 Alpha; IL-1 Alpha; Hematopoietin-1; IL1A; IL1F1 |
---|---|
Derived from | E.coli |
Purity | Greater than 95% as determined by reducing SDS-PAGE. |
Formulation | Lyophilized from a 0.2 μm filtered solution of 20mM TrisHCl, 150mM NaCl, pH 7.5. |
Shipping | The product is shipped at ambient temperature. |
Storage | Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.Reconstituted protein solution can be stored at 4-7°C for 2-7 days.Aliquots of reconstituted samples are stable at < -20°C for 3 months |
Reconstitution | Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in ddH2O. Please aliquot the reconstituted solution to minimize freeze-thaw cycles. |
Endotoxin | Less than 0.1 ng/ug (1 IEU/ug) as determined by LAL test. |
Background | Interleukin-1 alpha (IL1α) is a cytokine member of the interleukin-1 family. IL-1 consists of two distinct forms: IL1α and IL1β that recognize the same cell surface receptors but are distinct proteins with approximately 25% amino acid sequence identity. IL1α is constitutively produced by epithelial cells and plays an essential role in maintenance of skin barrier function. Upon stimulation, a wide variety of cells including osteoblasts, monocytes, macrophages can be induced to express IL1α. IL1α possesses a wide range of metabolic, physiological, haematopoietic activities, and is critically involved in the regulation of the immune responses and inflammatory responses. |
Recombinant Human Interleukin-1 alpha is produced by our E.coli expression system and the target gene encoding Ser113-Ala271 is expressed.
