1. Since applications vary, each investigator should titrate the reagent to obtain optimal results. 2. Please refer to us for technical protocols. 3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.

Application Notes
Immunofluorescent Staining and Flow Cytometric Analysis: The purified form of 2E2 can be used for the immunofluorescent staining (Less or equal than 1 µg antibody/10e6 cells) and flow cytometric analysis of normal mouse cells or cell lines to measure their expressed levels of IFN-gammaRalpha. An appropriate purified immunoglobulin isotype control is A19-3. A three-layer staining protocol is recommended for maximizing the detection IFN-gammaRalpha chains expressed by cells as detailed in the figure legend. 2E2 is a nonblocking antibody that can be used for the unobstructed immunofluorescent staining and flow cytometric analysis of cells in systems where the ligand (i.e., IFN-gamma) for IFN-gamma receptors is present. Immunoprecipitation: The 2E2 antibody has been reported to be useful for the immunoprecipitation of IFN-gammaRalpha chains from lysates of cloned mouse T cells.
The 2E2 antibody recognizes the extracellular region of the 90 kDa alpha chain subunit of the mouse interferon-gamma receptor (IFN-gammaRalpha, aka, CD119). The functionally active-form of the mouse IFN-gamma receptor consists of two (or more) subunits, with IFN-gammaRalpha responsible for IFN-gamma binding and both the IFN-gammaRalpha and IFN-gammaRbeta chains required for the transduction of biologic responses. IFN-gammaRalpha is expressed by a variety of cell lines and normal mouse cells (except mature erythrocytes) including T cells, B cells, NK cells, monocytes, neutrophils, fibroblasts, epithelial and endothelial cells. The 2E2 antibody is a non-neutralizing antibody, it does not block the binding of IFN-gamma to its receptor. The immunogen used to generate this hybridoma was a purified preparation of soluble recombinant mouse IFN-gammaRalpha chain protein. Synonyms: IFN-gamma Receptor alpha chain
