  • Immuno-dye reagent and assay for detection of endotoxin
    Patent number: 5093235
    Abstract: A novel immuno-dye reagent capable of detecting the presence of endotoxin in samples has been developed. The immuno-dye reagent comprises a solution of new methylene blue and an anti-endotoxin monoclonal antibody specific to a selected endotoxin. The immuno-dye reagent can be used in an assay to detect endotoxin by reacting the immuno-dye reagent with an endotoxin suspect pH adjusted sample, under hydrophobic conditions. The immuno-dye reagent can also be used in any application where binding of endotoxin is crucial, such as purifying endotoxin-contaminated solutions.
