FC - Quality tested

Recommended Usage:

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 5 µl per million cells or 5 µl per 100 µl of whole blood. It is recommended that the reagent be titrated for optimal performance for each application.

* Alexa Fluor® 647 has a maximum emission of 668 nm when it is excited at 633nm / 635nm.

The IL-18 receptor (IL-18R) complex is composed of two known chains, IL-18 receptor α (IL-18Rα) and IL-18 receptor β (IL-18Rβ). IL-18Rα (IL-1R5) is an IL-1 receptor super family member. It was originally described as IL-1 receptor-related protein (IL-1Rrp) because of its homology with the IL-1/Toll receptor family. IL-18Rα is the extracellular binding domain of the IL-18 receptor complex. It is expressed on the majority of peripheral CD4+ T cells, Th1 cells, and reciprocally repressed during Th2 development. The expression of IL-18Rα is induced by an IL-12/Stat4 pathway and inhibited by IL-4/Stat6 pathway. Binding of IL-18Rα together with IL-18β to proinflammatory cytokine IL-18 plays an important role in innate and autoimmune responses.

Other Names: IL-1 Rrp, CDw218a, IL-18 receptor a
