Genetics of the antibody response to dextran in mice.

The immune response to dextran having the alpha-1,3 linkage may be under the control of antibody structural genes. Mice that respond well to this antigen produce antibody restricted with respect to light chain class (lambda) and to an antigenic determinant resulting from a particular heavy and light chain interaction. The response to dextran is controlled by a locus linked to the-heavy chain locus.
