The present invention involves a method of assaying for modulators of enzymes involved in the phosphorylation of the inner core oligosaccharide of LPS. In particular, the method assays for modulators preferably inhibitors, of, WaaP, a tyrosine kinase responsible for the phosphorylation of HepI of the inner core LPS. The finding that monoclonal antibody mAb 7-4 specifically recognizes the phosphate group(s) of LPS is the basis for the development of, a non-radiolabeling ELISA-based assay for enzymes involved in the phosphorylation of LPS.
