Upon activation, DNA sensors and inflammasomes often polymerize into filamentous oligomers, and transduce the incoming pathogenic signal via inducing the assembly of downstream filaments. Given the complexity of these supramolecular structures, kinetics and thermodynamics that govern their assembly mechanisms remain poorly understood. Here, we present a simple yet robust assay that can track the assembly of these filaments in a quantitative manner. This FRET-based measurement is cost effective and also amenable to high-throughput screening.
