Purity:Purified by Protein A affinity chromatography.
Form:Supplied as a liquid in PBS, pH 7.2, 0.09% sodium azide. Labeled with fluorescein isothiocyanate (FITC).
Specificity:Can be used as a negative control for direct FITC immunofluorescence staining (eg. Flow Cytometry) when using mouse monoclonal antibodies to human cell surface antigens of isotype IgG2b. This enables an estimation of non-specific binding of mouse monoclonal antibodies to cell surface components in peripheral blood and tissue.
