[Immunoglobulins in swine. (B) Immunohistological studies on the localization of cells containing immunoglobulin in the tissues of the small intestine and spleen (author's transl)].

Antisera to porcine immunoglobulins, conjugated with flurescein isothiocyanate, were used in studies on the localization of cells containing immunoglobulin in the tissues of the intestine and spleen in pigs. Cells containing IgM and IgA were found to be present in the lamina propria of the intestinal mucosa, the villous membrane showing fluorescence due to liberated immunoglobulins. Cells containing IgG and IgM were detected in the marginal areas of the splenic lymph nodes but could not be definitely identified as mature plasma cells.
