title: Immunoglobulin isotype in the murine response to polysaccharide antigens.
abstract: Murine antisera specific for the alpha (1 leads to 3) and alpha (1 leads to 6)-linked glucosyl determinants of dextran, as well as for meningococcal polysaccharide group C, have been examined for the distribution of their immunoglobulin classes and subclasses. Whereas the thymus-independent anti-alpha (1 leads to 3) dextran response in BALB/c mice was found to be IgM greater than IgG3 greater than IgA, thus corresponding to previously published work, neither the alpha (1 leads to 6) response in its thymus-dependent or-independent form, nor the response to purified meningococcal polysaccharide, corresponded to this pattern. No preference for any of the IgG subclasses appeared for these antigens when given as thymus-independent carbohydrates. On the other hand, thymus-dependent forms of alpha (1 leads to 6) dextran showed an IgG1 greater than IgG3 greater than IgG2 pattern.
