Recombinant Human IL18 Protein, Tyr37-Asp193, Tag Free, Biotinylated

• Cat.No.: IL18-133H
• Product Overview: Recombinant human IL-18-No Tag protein was developed from HEK293 and has a target region of No Tag.

Specification

• Species: Human
• Source: HEK293
• Tag: Non
• Protein Length: Tyr37-Asp193
• Description: The protein encoded by this gene is a proinflammatory cytokine of the IL-1 family that is constitutively found as a precursor within the cytoplasm of a variety of cells including macrophages and keratinocytes. The inactive IL-18 precursor is processed to its active form by caspase-1, and is capable of stimulating interferon gamma production, and of regulating both T helper (Th) 1 and Th2 responses. This cytokine has been implicated in the injury of different organs, and in potentially fatal conditions characterized by a cytokine storm. In humans, IL-18 gene is located on chromosome 11. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.
