Neutralization Activity: Neutralization activity may be measured with a proliferation assay using 60 pg/mL recombinant human IL-15 (Cat. No. 560254) to stimulate murine CTLL-2 cells at 2x10^4 cells/mL as indicator cells (i.e preincubation of the antibody with recombinant human IL-15 for 60 minutes). 50% Neutralization (ND50) at 0.02 - 3.0 µg/mL > 85% Neutralization at 2-20 µg/mL

The 4G3 antibody reacts with the common gamma subunit (gammac) shared by the IL-2, IL-4, IL-7, IL-9 and IL-15 receptors also known as CD132. This receptor is expressed constitutively at low levels on most lymphocytes, myeloid cells, embryonic thymocytes and lymphoid cell lines, but not non-lymphoid cells. The gammac receptor is a 75 - 80 kD transmembrane glycoprotein which mediates signal transducing activities of cytokine receptor complexes with which it is associated. Synonyms: Common gamma chain, gammac
