Can CF® Dyes be used to label lipopolysaccharide (LPS) for in vivo studies?

We do not have firsthand experience with LPS labeling, but according to the literature,  LPS has been labeled using amine-reactive dyes, like FITC. Our amine-reactive CF® Dye Succinimidyl Esters should also work for this. There is a publication for enzymatic labeling of LPS using dye hydrazides. Our CF® Dye hydrazides could be used in this method. The paper also describes the traditional amine labeling method and purification of the conjugate.
