Lumit® IL-2 (Human) Immunoassay

Quantify Cytokine Release Without Tedious Wash Steps

The Lumit® IL-2 Immunoassay quantitatively measures released IL-2 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.

Note: The total number of assays per kit will vary based on final well volume.

For standard well volumes:

100 assay kits: applicable for 100 assays in 96-well plates or 400 assays in 384-well plates.
500 assay kits: applicable for 500 assays in 96-well plates or 2,000 assays in 384-well plates.
1,000 assay kits: applicable for 1,000 assays in 96-well plates or 4,000 assays in 384-well plates.

How the Lumit® IL-2 Immunoassay Works

Primary antibodies to IL-2 were selected for their specific and sensitive detection and labeled with the LgBiT and SmBiT subunits of NanoBiT® Luciferase. In the presence of IL-2, the subunits are brought together to form an active luciferase enzyme. Addition of optimized substrate generates a bright luminescent signal proportional to IL-2 levels.

Detect IL-2 Release as a Marker of T Cell Activation

Data showing IL-2 release as a marker of T cell activation — Purified CD8+ T cells (effector cells) were combined with Raji B cells (target cells) and a serial dilution of Blincyto® (CD3 and CD19 bispecific T cell engager). The Lumit® IL-2 (Human) Immunoassay reagents were added directly to treated cell wells to detect IL-2 release from the T cells.

Lumit® IL-2 Immunoassay is Scalable for High-Throughput Applications

Example data from Lumit IL-2 assay in 96- and 384-well format

Human PBMCs were plated in 96-well plates (left) or 384-well plates (right) at 40,000 cells/well or 10,000 cells/well, respectively, and treated with a cell stimulation cocktail to induce IL-2 release. The Lumit® IL-2 Immunoassay reagents were added directly to the cell culture wells. The calculated EC₅₀ values are similar in the 96-well plate and 384-well plate formats.
