Target Background

Interleukin-1 beta (IL-1b) plays a critical role in immune and inflammatory responses. It is produced in response to infection, inflammatory agents, and endotoxins. It also plays an important role in bone remodeling, fever, and metabolism of carbohydrates. Increased production of IL-1b is responsible for a variety of autoinflammatory syndromes.

This kit worked very will with human serum samples. Great sensitivity!

This ELISA kit was used for quantification of IL-1 beta cytokine in the supernatants of peripheral blood mononuclear cells upon stimulation with genotoxics in a dose- and time dependent manner. The optical density (O.D.) values obtained were repetitive.
