Recombinant Rat Interleukin 33

• Cat.No.: Il33-286R
• Product Overview: Recombinant rat IL-33 (aa 109-264) was expressed in E. coli, ~16kDa.

Specification

• Species: Rat
• Source: E.coli
• Tag: Non
• Protein Length: 109-264 a.a.
• Description: IL-33 is a new member of the IL-1 family. It is involved in T helper type 2 response via the activation of its receptor ST2 (IL-1RL1) driving the production of Th2-associated cytokines. The stimulation of ST2 by IL-33 induces the NF-κB and MAPK pathways. The human IL-33 protein is expressed with a prodomain (aa 1-111) which is cleaved by caspase-1 to produce the 18kDa mature protein (112-270).
