• Species Reactivity

  Cotton Rat

• Specificity

  Detects cotton rat IL‑1 alpha /IL‑1F1 in direct ELISAs and Western blots. In Western blots, approximately 40% cross-reactivity with recombinant rat IL-1 alpha is observed, 15% cross-reactivity with recombinant mouse IL-1 alpha is observed, and less than 1% cross-reactivity with recombinant human IL-1 alpha and recombinant porcine IL-1 alpha is observed.

Background: IL-1 alpha/IL-1F1

IL-1 alpha (Interleukin-1 alpha) is a cytokine that is induced during microbial exposure and promotes the release of multiple inflammatory mediators and acute phase proteins. It also supports hematopoietic stem cell expansion, promotes neutrophil mobilization from the bone marrow, and promotes osteoclast formation. IL-1 alpha signals through a receptor complex composed of IL-1 RI and IL-1 RAcP. It also binds the decoy receptor IL-1 RII which associates with IL-1 RAcP but does not transduce signaling.
