Used to measure interleukin-1 alpha (IL-1α) levels in biological samples such as serum, plasma, or cell culture supernatants from rats. It is commonly applied in research settings to study inflammatory responses, immune system activation, and disease mechanisms involving inflammation, such as arthritis, sepsis, and autoimmune disorders. The kit enables accurate quantification of IL-1α protein, supporting studies in pharmacology, toxicology, and immunology where monitoring cytokine expression is essential. Its high sensitivity and specificity make it suitable for detecting low concentrations of IL-1α in small sample volumes.
