Detection and quantitation of endotoxin by fluorescence polarization

摘要

Fluorescently labeled ENP as well as methods of preparation are disclosed. Also disclosed is a method of detecting endotoxin in a liquid sample suspected of containing endotoxin, comprising admixing said liquid sample with fluorescently labeled ENP for a time sufficient to form a complex between the labeled ENP and the endotoxin, and performing fluorescence polarization experiment on the sample, wherein a change in the fluorescence polarization indicates the presence of endotoxin.
