The Lumit™ IL-4 Immunoassay quantitatively measures released IL-4 in cell culture samples using a simple, no-wash protocol. Just add labeled antibodies to the sample, add detection reagent and read luminescent signal using a standard plate-reading luminometer. The entire protocol is completed in less than 70 minutes! The assay can be used directly on cells in culture or culture medium transferred to a separate assay plate.
Primary antibodies to IL-4 were selected for their specific and sensitive detection and labeled with the LgBiT and SmBiT subunits of NanoBiT® Luciferase. In the presence of IL-4, the subunits are brought together to form an active luciferase enzyme. Addition of optimized substrate generates a bright luminescent signal proportional to IL-4 levels.
The pg/ml to ng/ml linear range of Lumit™ detection covers expected concentrations for most cell models.

When treated with a Cell Stimulation Cocktail (CSC), T helper type 2 (Th2) cells and human PBMCs (PBMC) each release low levels of IL-4. Following 24 hours of CSC treatment, Lumit™ IL-4 Immunoassay reagents were added directly to cell wells to measure IL-4 release.
Human T helper type 2 (Th2) cells were plated in 96-well plate format, primed overnight with hIL-2 and treated with increasing concentration of cell stimulation cocktail (CSC) for 24 hours. Following treatment, CellTox™ Green Cytotoxicity Assay and the Lumit™ IL-4 (Human) Immunoassay reagents were added to determine cytotoxicity and IL-4 release. CellTiter-Glo® Cell Viability Assay reagent was added to determine cell viability. A dose-dependent increase in IL-4 was observed, with some degree of increased cytotoxicity and decreased cell viability.
