Tissue and ultrastructural localization of 5-hydroxytryptamine (serotonin) in the tissues of Ascaris suum with energy dispersive X-ray spectrometry of immunoreactive structures.


Muscle, hypodermis and gastrointestinal epithelial cells from adult female Ascaris lumbricoides var. suum were found to contain serotonin based upon glyoxylic acid induced histofluorescence and indirect immunolabeling with an antiserotonin monoclonal antibody conjugated to protein A-colloidal gold. Histofluorescence indicated that muscle-hypodermis and… (More)
