Serology detects antibodies against malaria parasites, using either an indirect immunofluorescence assay (IFA) or an enzyme-linked immunosorbent assay (ELISA).
By metaphase the oscillations may be of such high frequency that they would be difficult to detect, but the lower frequency oscillations early in prometaphase should be detectable by immunofluorescence microscopy and high-speed camera technology.
Viral antigens may sometimes be shown in tissue samples using immunofluorescence or EIA.
The work has involved the use of such advanced techniques as electron microscopy, autoradiography, radioisotope and immunofluorescence labelling of specific proteins, plus the full armoury of modern cell biology.
Liver tissue with metastases was additionally analyzed for cytokines, T cell markers and Fas/Fas-L expression using immunohistochemistry, immunofluorescence and RT-PCR.
By immunofluorescence, beclin-1 staining showed faintly detectable and diffusely distributed in the cytoplasm (regarded as negative) or confined to the perinuclear region as large and brilliant puncta suggestive of macro-aggregate reactivity (regarded as positive).
T. cruzi infection as detected by ELISA, hemagglutination, and immunofluorescence exams, and by the parasite DNA signature.
The remaining Chagas patient infections were identified by enzyme-linked immunosorbent assay (ELISA), hemagglutination and immunofluorescence assays, which showed specific anti -
