Localization of antigenic activity and immunogenic capacity in different conformational domains of procollagen peptide.
The antibody response to the amino-terminal CNBr peptide of sheep procollagen which consists of a globular and a collagenous segment, was studied in inbred strains of mice. The determinants reacting with antibody could be localized in the globular domain and were lost by reduction of disulfide bridges. The ability to induce an antibody response required the collagen-like sequences and was independent of the triple-helical conformation of this segment. The data were interpreted as indicating a different conformation dependence of hapten and carrier determinants.
