Lumit™ HMGB1 Human/Mouse Immunoassay

Fast, No-Wash Detection of HMGB1

High-Mobility Group Box 1 (HMGB1) functions as a damage-associated molecular pattern (DAMP) released from cells in inflammatory responses. HMGB1 is often measured as a key biomarker of immunogenic cell death, a specialized form of cell death that results in an immune response. HMGB1 also functions as a proinflammatory cytokine. Current methods to detect HMGB1, such as ELISA, require tedious wash steps and lengthy protocols. Lumit™ technology simplifies HMGB1 quantitation with an add-mix-measure protocol completed in 90 minutes or less.

How the Lumit™ HMGB1 Immunoassay Works

Primary antibodies to HMGB1, selected for their specific and sensitive detection, are labeled with the LgBiT and SmBiT subunits of NanoBiT® Luciferase. In the presence of HMGB1, the subunits are brought together to form an active luciferase enzyme. Addition of optimized substrate generates a bright luminescence signal proportional to HMGB1 levels. The assay detects both human and mouse HMGB1.

Large Dynamic Range of HMGB1 Detection

Due to the homology of human and mouse HMGB1, the kit can be used for both species with minimal performance differences.

Detect Drug-Induced Immunogenic Cell Death in Various Cell Culture Models

Drug-induced immunogenic cell death detected with HMGB1 assay.

Human U2OS cells (left) and mouse EL4 cells (right) were treated with doxorubicin for 24 hours. After 24 hours, the Lumit™ HMGB1 Immunoassay was performed directly on cell culture samples to measure HMGB1 released from treated cells.
