Purity |
> 97 % by SDS-PAGE and HPLC analyses. |
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 0.005 ng/ml, corresponding to a specific activity of > 2.0 ¡¿ 108 IU/mg. |
Physical Appearance |
Sterile Filtered White lyophilized (freeze-dried) powder. |
Formulation |
Lyophilized from a 0.2 µm filtered concentrated solution in 20 mM Tris, 150 mM NaCl, pH 8.5. |
Endotoxin |
Less than 1 EU/µg of rRtIL-1¥á as determined by LAL method. |
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 ¡Â -20 ¡ÆC. Further dilutions should be made in appropriate buffered solutions. |
Stability & Storage |
Use a manual defrost freezer and avoid repeated freeze-thaw cycles. - 12 months from date of receipt, -20 to -70 ¡ÆC as supplied. - 1 month, 2 to 8 ¡ÆC under sterile conditions after reconstitution. - 3 months, -20 to -70 ¡ÆC under sterile conditions after reconstitution. |
Usage |

Background |
Interleukin-1 alpha (IL-1¥á) 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-1¥á and IL-1¥â binds to the same receptor and has similar but not identical biological properties. Recombinant rat IL-1 alpha contains 150 amino acids which is a single non-glycosylated polypeptide. |
