Abstract:
Spectral data and nucleic acid complex formation properties for more than 30 both newly synthesized and widely used fluorescent nucleotide-specific compounds of various classes have been analyzed. These include phenylbenzene, bisbenzimidazole, psoralen, angelicin, tetrahydrocarbazole, oxophenoxazine, and others. The main rules of a generalized model adequately explaining changes in fluorescent properties of synthetic, low molecular weight nucleotide-specific dyes depending on their chemical structure, mode of interaction with substrate, properties of assay medium, etc. are proposed. Fluorescent nucleotide-specific dyes have been originally used in newly developed methods for: express evaluation of "generalized microbial dissemination" of liquid media; evaluation of possible genotoxic effects of various foodstuffs, pharmaceutical drugs, hazardous environmental factors (including their combined effects on living organisms), etc.

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...
