Interaction between MenB capsular polysaccharide and microtubules in coimmunoprecipitation experiments. Bacterial cell extracts enriched in capsular polysaccharide (cps) from MenB strain B1940 or MenC strain 93/4286 were challenged with precleared HeLa cell lysate in coimmunoprecipitation assays by using mouse anti-α-tubulin antibody cross-linked to a resin. Coimmunoprecipitates and control extracts were then analyzed by immunoblotting with anti-α-tubulin and anti-MenB or anti-MenC capsule antibodies.
