Cytokine Detection with Lumit™ Immunoassays

Lumit™ Immunoassays for cytokine detection quantitatively measure target analytes in cell culture samples with a simple, no-wash assay protocol. The assays can be performed directly on cell culture samples or on medium transferred from cell plates.

Lumit™ Cytokine Detection Immunoassay Overview

Primary antibodies to the target are used to detect the cytokine. The antibodies, selected for their specific and sensitive detection of the targets, are labeled with the LgBiT and SmBiT subunits of NanoBiT® Luciferase. In the presence of the target, the subunits are brought together to reconstitute active luciferase enzyme. Upon addition of the optimized substrate, a bright luminescent signal is generated.

The protocol simply requires addition of the labeled antibodies to the sample, addition of the detection reagent and reading of the luminescent signal. The entire protocol is completed in less than 70 minutes.

Applications

Quantifying IFN-γ to Measure T Cell Activation

Effector cells (purified CD8+ T cells) and target cells (Raji B Cells) were combined with Blincyto®, a bispecific T-cell engager. The Lumit™ IFN-γ Immunoassay was performed directly in cell culture wells to quantify IFN- γ as a measure of T cell activation.

Benefits

No wash, no transfer: The simple add-mix-read protocol can be performed directly on cell cultures.
Rapid time to results: Get results just 70 minutes after starting the assay.
Large linear range: The picomolar to nanomolar linear range covers expected concentrations for the majority of cell models.
Scalable and high throughput: Perform the assays in low volumes in 96-well or 384-well plates; precoated plates not required.
Luminescence detection: Use a standard plate-reading luminometer; no specialized instruments or modules required.
