Embodiment Construction

[0510] I. Definition

[0511] "Isolated" as used herein refers to a protein in a non-native environment, especially isolated from nature, eg, the term does not include proteins in vivo, nor in samples taken from the human or animal body. Typically, the protein will be in a carrier such as a liquid or medium, or can be formulated, frozen or lyophilized, and all of these forms are encompassed by "isolated" as appropriate. In one embodiment, separated does not refer to the protein in a gel, such as a gel or the like used in Western blot analysis.

[0512] IL-33 protein as used herein refers to interleukin 33, especially mammalian interleukin 33 protein, eg the human protein deposited under UniProt number 095760. However, in light of the findings of the inventors, it is evident that this entity is not a single species but exists in reduced and oxidized forms. Given the rapid oxidation of the reduced form in vivo, for example within a period of 5 minutes to 40 minutes, and in vit...
