Human IL-18 Instant ELISA

Description: The human IL-18 Instant ELISA is an enzyme-linked immunosorbent assay for the quantitative detection of human IL-18. The human IL-18 Instant ELISA is for in vitro diagnostic use. Not for use in therapeutic procedures.

Formerly called interferon gamma inducing factor (IGIF), IL-18 is a cytokine that plays an important role in the Th1 response, primarily by its ability to induce IFN gamma production in T cells and natural killer cells.
In terms of structure, IL-18 and IL-1 beta share primary amino acid sequences of the so-called "signature sequence" motif and are similarly folded as all beta pleated sheet molecules. Also similar to IL-1 beta, IL- 18 is synthesized as a biologically inactive precursor molecule lacking a signal peptide which requires cleavage into an active, mature molecule by the intracellular cysteine protease called IL-1 beta-converting enzyme (ICE, caspase-1). The activity of the mature IL-18 is closely related to that of IL-1.
The activity of IL-18 is via an IL-18 receptor complex. IL-18 induces gene expression and synthesis of TNF, IL-1, Fas Ligand, and several chemokines. Similar to IL-1, IL-18 participates in both innate and acquired immunity.
