| pubmed-article:2728697 | pubmed:abstractText | Samples of Vi-antigen subjected to hydrolysis of different duration have been studied. As revealed in this study, 12-hour hydrolysis causes the depolymerization of the preparation. The fragments thus obtained have been found to possess Vi-specificity. The polymeric form of Vi-antigen contains adhesin differing in specificity from Vi-determinant. This component is absent in the low-molecular fraction of Vi-antigen. Adhesin is the binding element of the molecule of Vi-antigen and ensures its polymeric structure. | lld:pubmed |
