Detection of "neutral" type 7F and type 14 pneumococcal capsular polysaccharides by immunoelectrophoresis
Journal of Clinical Microbiology
|June 1, 1982
Abstract:
Type 7F and type 14 pneumococcal capsular polysaccharides, neutral at pH 8.6, were studied by immunoelectrophoresis at pH 5. Three techniques were used: rocket, countercurrent, and reversed immunoelectrophoresis. Our results show that these two capsular polysaccharides types can be detected at pH 5 with high sensitivity.
