Appearance Lyophilized powder. Formulation Lyophilized after extensive dialysis against PBS. Endotoxin Level <0.2 EU/μg, determined by LAL method. Reconstitution Reconstitute the lyophilized recombinant Rat Interleukin-1 alpha (CHO-expressed) (rRtIL-1α) to 100 µg/mL using ddH2O or diluted with PBS. Storage & Stability Lyophilized recombinant Rat Interleukin-1 alpha (CHO-expressed) (rRtIL-1α) is stored at -20°C. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer. It is recommended to freeze aliquots at -20°C or -80°C for extended storage. Shipping Room temperature in continental US; may vary elsewhere. Background IL-1alpha and IL-1beta have potent effects on the central nervous system resulting in fever, activation of the hypothalamic-pituitary-adrenal axis and behavioural depression. IL-1alpha and IL-1beta show some species specificity in the potency of their biological activities, the objective of the present work was to directly compare the effects of recombinant rat IL-1alpha and IL-1beta in the rat system as a first step to dissect out the mechanisms that are involved in these effects. In vitro, recombinant rat IL-1alpha and IL-1beta bind with the same affinity as human IL-1 to the rat insulinoma Rin m5F cell line that mainly expresses type I IL-1 receptors. This binding activated IL-1 receptors, as shown by induction of the synthesis of TNF-alpha mRNA. In vivo, recombinant rat IL-1alpha and IL-1beta enhance body temperature, increase plasma levels of corticosterone and ACTH, and depress social behavior[1]. |
