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.

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.

Simple One-Plate Protocol, No Wash Steps

Large Dynamic Range of Lumit® IL-2 Detection

The pg/ml to ng/ml linear range of Lumit® detection covers expected concentrations for most cell models.

Dynamic Range	28.2pg/ml – 25ng/ml
Minimal Detectable Dose (MDD)	7.2pg/ml (2 SD above background)
Assay Time	70 minutes
Sample Type	Cell culture supernatants

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.
