Abstract
The capsular substance of H. influenzae type b was isolated in a highly purified form. Serologic identity was demonstrated among the polysaccharides of seven different strains of H. influenzae type b. The polysaccharide had a molecular weight greater than 200,000 estimated by gel filtration and 152,000 by analytic ultracentrifugation and was shown to be relatively non-toxic and non-pyrogenic for laboratory animals.Keywords
