Abstract: | Tolerance production is readily induced by inoculation of heterologous serum proteins in mice. The intravenous and intraperitoneal route are generally preferred because they allow rapid antigen equilibrium in the intra and extravascular spaces of the host. This report shows that the administration of particle-free antigen in the foot pad produces a greater number of tolerant animals at all concentrations used. The active participation of regional lymph nodes in tolerance production is postulated. |
