Description
The GIR-208 antibody recognizes the extracellular region of CD119 which is also known as the alpha chain subunit (80-95 kDa glycoprotein) of the human interferon- γreceptor (IFN- γR α ). The functionally active-form of the human IFN- γreceptor consists of two (or more) subunits, with IFN- γR α responsible for IFN- γβ chains required for the transduction of biologic responses. The IFN- γreceptor α chain (CD119) is expressed on the surface of most human cells (except mature erythrocytes) including monocytes, macrophages, T cells, B cells, NK cells, neutrophils, fibroblasts, epithelial cells, and endothelium. Binding of 125I-labeled GIR-208 antibody to IFN- γR α + cells is reported to be specifically inhibited in the presence of excess IFN- γ. GIR-208 does not cross react with IFN- γas tested by ELISA. The ability of this antibody to bind to IFN- γreceptors of species other than human has not been determined. The immunogen used to generate this hybridoma was human IFN- γR α purified from human placenta. The GIR- 208 has been reported to block the binding of 125I-human IFN-γto IFN-γRα+ cells as well as purified, soluble human IFN-γRα. GIR-208 is a neutralizing antibody that has been shown to neutralize the anti-viral activity of IFN-γon WISH cells in a dose-dependent fashion.
