Research Abstract

We have established a novel measurement system for the NF-κB activity using fluorescence correlation spectroscopy (FCS), which was a methodology to examine the size and number of fluorescence-labeled molecules in a confocal area by direct observation of their Brownian motion in solutions. The principle of the measurement was to detect the different of molecular weights of fluorescent-labeled DNA probe and DNA probe-NF-κB complex. The elevation of NF-κB activity reflects the acute inflammation. Measuring the NF-κB activity in the patients with systemic inflammatory response syndrome (SIRS) would be useful as an inflammatory marker.
