Recombinant Mouse IL-1 alpha
Interleukin-1 alpha (IL-1α) is a non-secreted proinflammatory cytokine 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. Both IL-1α and IL-1β binds to the same receptor and has similar if not identical biological properties. Among various species,the amino acid sequence of mature IL-1α s conserved 60 % to 70 % and human IL1 has been found to be biologically active on murine cell lines

Appearance |
Sterile Filtered White lyophilized (freeze-dried) powder. |
|
Stability & Storage |
Use a manual defrost freezer and avoid repeated freeze-thaw cycles. - 12 months from date of receipt, -20 to -70 °C as supplied. - 1 month, 2 to 8 °C under sterile conditions after reconstitution. - 3 months, -20 to -70 °C under sterile conditions after reconstitution. |
|
Formulation |
Lyophilized from a 0.2 µm filtered solution in PBS, pH 7.4. |
|
Reconstitution |
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20 °C. Further dilutions should be made in appropriate buffered solutions. |
|
Biological Activity |
Fully biologically active when compared to standard. The ED50 as determined by a cell proliferation assay using murine D10S cells is less than 2 pg/ml, corresponding to a specific activity of > 5.0 × 108 IU/mg. |
|
Shipping Condition |
Gel pack. |
|
Handling |
Centrifuge the vial prior to opening. |
|
Usage |
For Research Use Only! Not to be used in humans. |
