Synthesis of IgG, IgA, IgM by chicken tissues: immunofluorescent and 14C amino acid incorporation studies.

Abstract Chicken tissues have been studied with immunofluorescent techniques to establish the distribution and relative numbers of cells stained specifically with anti-α, -µ, and -γ antisera. In the gut, IgA predominated; most numbers of IgA cells were found in the duodenum, and less further down the intestinal tract. The cecal tonsil contained mostly IgG, followed by IgM cells. Only a few IgA cells were seen in the cecal tonsil. The spleen …
