Occurrences, specificities, and functions of ubiquitous antibodies in human serum that are reactive with the Cryptococcus neoformans cell wall.

abstract：:A unique enzyme-linked immunosorbent assay was developed to detect soluble peptidoglycans in biological fluids. It makes use of the similar affinities of vancomycin and purified rabbit antibodies to peptidoglycan precursor sequences found in soluble peptidoglycans. This assay has been used to detect as little as 500 p...
