Immunoglobulin determinants on the surface of lymphoid cells of carps

Abstract
Immunoglobulin determinants were detected by indirect immunofluorescence on the surface of numerous lymphocytes of perpheral blood, spleen, and pronephros of craps. The most interesting finding was the high proportion (65–68 %) of Ig+ lymphocytes in the thymus of early adult carps, possibly related to thymus function.
