Abstract
Extract
Sporidesmin, the causative agent of facial eczema, is a low molecular weight (473) hepatotoxin produced by the fungus Pithomyces chartarum. Being a small molecule, it is unlikely that sporidesmin would be capable, by itself, of inducing an antibody response in an animal. However, an antibody response can often be produced against a low molecular weight molecule, provided that the molecule, is covalently coupled to a protein with a molecular weight of approximately 10 000 or greater.
