Fluorescent probes for detection of protozoan parasites
1Fumihiko Kawamoto and Nobuo Kumada are at the Depatment of Medical Zoology, Nagoya University School of Medicine, Nagoya 466 Japan.
Abstract:
Fluorescent probes generally provide a rapid and simple staining technique, valuable for the rapid diagnosis of protozoal infections. However, many of these staining techniques have disadvantages for clinical tests: (I) they require a fluorescence microscope which is not always available in clinical laboratories; (2) the preparations are not permanent because the fluorescent probes do not withstand dehydration; (3) variable quenching of the fluorescence may occur, unless proper preventive measures are taken. In this article, Fumihiko Kawamoto and Nobuo Kumodo explain some of the most widely used fluorescent probes, and discuss how problems in their use can be minimised.

Labeling DNA Probes
Radioisotopes, fluorophores, or small molecule binding partners like biotin or digoxigenin, are the most widely used reporter tags for labeling DNA probes. These labels can be attached to the probe DNA molecule via...

Protein Dynamics in Living Cells
Fluorescent recovery after photobleaching (FRAP) is a fluorescent-protein-based detection technique used to quantify protein movement rates within the cell. This method exposes a small portion of the cell to an intense laser beam. The laser beam causes permanent photobleaching of the fluorophore-tagged proteins in the exposed region. As the bleached...
