Lyophilized from a 0.2 µm filtered solution in PBS, pH 7.4, with 5 % trehalose, 0.02 % Tween-20. |
| Reconstitution |
It is recommended that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute the lyophilized powder in sterile distilled water or aqueous buffer containing 0.1 % BSA to a concentration of 0.1-1.0 mg/ml. |
| Storage & Stability |
Upon receiving, this product remains stable for up to 6 months at -20°C or -70°C. Upon reconstitution, the product should be stable for up to 1 week at 2-8°C or up to 3 months at -20°C. Avoid repeated freeze-thaw cycles. |
| Target Background |
Interleukin-1beta (IL-1β) 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-1αand IL-1β binds to the same receptor and have similar but not identical biological properties. The mature rat IL1β shares 90 % a.a. sequence identity with cotton rat and mouse and 65 % to 77 % with canine, human,and rhesus IL1β. |
