A 1H NMR method for the analysis of antigen-antibody interactions: binding of a peptide fragment of lysozyme to anti-lysozyme monoclonal antibody.

abstract：:Recent studies by our group suggested that lysozyme has a high affinity for bacterial lipopolysaccharide (LPS) of both the smooth and rough forms, and inhibits various immunomodulatory activities of LPS. GLA60 is a synthetic monosaccharide analogue of bacterial lipid A well known as having most of the activities of li...
