[The role of adhesin in the polymeric structure of Vi-antigen]
Abstract:
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.

Antibody Structure
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.
