Localization of tetrodotoxin in the skin of a brackishwater puffer Tetraodon steindachneri on the basis of immunohistological study

摘要

A monoclonal antibody-based immunoassay for localization of tetrodotoxin (TTX) in the skin of a brackishwater puffer Tetraodon steindachneri. is described in this paper. TTX was recognized in the undifferentiated basal cells and succiform cells in the skin under light microscope. Malpighian cells of the skin did not exhibit any TTX antigen. Neither gland nor enclosed gland-like apparatus possessing TTX was apparent in the skin.
