The transmission electron microscope (TEM) is used as an important diagnostic tool to screen human tissues at high magnification (the ultrastructural level), often in conjunction with other methods, particularly light microscopy and immunofluorescence techniques.
Pauci-immune (pauci- Latin: few, little) is a general term used to refer to a form of vasculitis that is associated with minimal evidence of hypersensitivity upon immunofluorescence and a lack of Anti-glomerular basement membrane antibody.
Supravital staining can be combined with cell surface antibody staining (immunofluorescence) for applications such as FACS analysis.
