Extractability of cell wall polysaccharide from lactobacilli and streptococci by autoclaving and by dilue acid.

abstract：:Monoclonal antibodies against 12 of the 17 IATS serotype strains of Pseudomonas aeruginosa were produced. Eighty-seven hybridoma clones were isolated, and the antibodies secreted were found to be reactive with both Formalin-fixed whole cells and purified lipopolysaccharide of homologous strains in enzyme-linked immuno...
