Quantify IFN-β Release Without Tedious Wash Steps
IFN-β is an essential mediator of the innate immune response. It has potent antiviral properties, regulates the activity of various immune cells, and exhibits anti-inflammatory effects. IFN-β is used as a therapeutic agent to mitigate inflammation in diseases such as multiple sclerosis.
The Lumit® IFN-β Immunoassay quantitatively measures released IFN-β 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® IFN-β Immunoassay Works
Primary antibodies to IFN-β were selected for their specific and sensitive detection and labeled with the LgBiT and SmBiT subunits of NanoBiT® Luciferase. In the presence of IFN-β, the subunits are brought together to form an active luciferase enzyme. Addition of optimized substrate generates a bright luminescent signal proportional to IFN-β levels.
Simple One-Plate Protocol Requires No Wash Steps
Broad Linear Range of Lumit® IFN-β Detection
The pico- to nanomolar linear detection range of the Lumit® IFN-β Immunoassay covers expected concentrations for most cell models.

Featured Webinar
Optimizing the Lumit® IL-6 Immunoassay for High-Throughput Drug Screening
In this webinar, we share key considerations for scaling Lumit® Immunoassays from a single 96-well plate to many 364-well plates and offer tips for optimizing Lumit® Immunoassays for HTS applications. You will also hear Galapagos scientist Dr. Nick Verstraeten share how his team used the Lumit® IL-6 Immunoassay in a screening campaign for antiviral drugs.
