Detection of "neutral" type 7F and type 14 pneumococcal capsular polysaccharides by immunoelectrophoresis

S C Szu et al. J Clin Microbiol. 1982 Jun.

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.
