This antibody neutralizes natural and recombinant rat IFN-y. Cross-reactivity to human IFN-y is less than 0.01% of the homologous combination. Biological Activity: >2.5 x 10^4 neutralizing units/mg, where one neutralizing unit is defined as the amount of antibody sufficient for neutralizing one unit recombinant rat IFN-y (~150 pg) in an antiviral activity bioassay.
For immunohistochemistry applications, it is recommended that the reconstituted antibody be dialyzed against PBS to remove trehalose.
Storage and reconstitution: store the lyophilized antibody at 2-8°C. Reconstitute using 0.5 mL sterile distilled water. Upon reconstitution, the antibody may be stored at 2-8°C for up to several weeks. For maximal stability, apportion the reconstituted antibody into working aliquots and store at -20°C, avoiding repeated freeze/thaw cycles. 0.02% sodium azide may be added to prevent bacterial growth.
IFN gamma, also called Type II interferon, macrophage activation factor, and immune interferon is produced primarily by T-lymphocytes and natural killer cells in response to antigens, mitogens, Staphylococcus enterotoxin B, phytohemaglutanin and other cytokines. IFN gamma is a glycoprotein that exists, functionally, as a homodimer of approximately 45 kDa. On SDS-PAGE it appears as a combination of 25, 20 and minor 15.5 kDa bands as a result of differential glycosylation. The biological activity of the IFN gamma homodimer is highly species specific and includes the following: antiviral activity, tumor antiproliferative activity, induction of class I and II MHC, macrophage activation, and enhanced immunoglobulin secretion by B lymphocytes. IFNg is involved in cytokine regulation and also acts synergistically with other cytokines.
