Wechselwirkungen von Transkriptionsfaktoren (TFs) mit der RNA-Polymerase werden in der Regel mit Pulldown-Assays untersucht. Wir wenden eine Biolayer Interferometry (BLI) Technologie an, um die Wechselwirkung von GrgA mit der Chlamydien-RNA-Polymerase zu charakterisieren. Im Vergleich zu Pulldown-Assays erkennt BLI Echtzeit-Assoziation und Dissoziation, bietet eine höhere Empfindlichkeit und ist sehr quantitativ.
