An immunoelectron micrograph of a muscle larva including the body wall (upper panel) and stichocyte granules (lower panel), which are immunostained with serum taken from a patient infected with Trichinella.
The immunoreaction is visualised by the second reaction with protein A tagged colloidal gold.
