よくあるご質問(FAQ)
How do SYTO dyes bind to DNA?
The binding mode of SYTO nucleic acid stains is unknown. However, the behavior of these and related nucleic acid dyes suggests the following binding properties:
1.They appear to contact the solvent (suggested by sensitivity to salt, divalent cations, and in particular, SDS) and thus are likely to have contacts in the grooves.
2.All SYTO dyes appear to show some base selectivity and are thus likely to have minor groove contacts.
3.They can be removed from nucleic acid via ethanol precipitation; this characteristic is not shared by ethidium bromide and other intercalators. Likewise, the dyes are not removed from nucleic acid via butanol or chloroform extraction. These extraction methods do remove ethidium bromide from nucleic acid.
4. SYTO binding is not affected by nonionic detergents.
5. SYTO dyes are not quenched by BrdU, so they do not bind nucleic acids in precisely the same way as Hoechst 33342 and DAPI ((4′,6-diamidino-2-phenylindole).
SYBR Green I has shown little mutagenicity on frameshift indicator strains, indicating that it isn't likely to strongly intercalate.
The protein tyrosine phosphatase PTP-BL associates with the midbody and is involved in the regulation of cytokinesis.
Authors:Herrmann L, Dittmar T, Erdmann KS
Journal:Mol Biol Cell
PubMed ID:12529439
'PTP-BL is a highly modular protein tyrosine phosphatase of unknown function. It consists of an N-terminal FERM domain, five PDZ domains, and a C-terminally located tyrosine phosphatase domain. Here we show that PTP-BL is involved in the regulation of cytokinesis. We demonstrate localization of endogenous PTP-BL at the centrosomes during ... More
Nucleic acid binding agents exert local toxic effects on neurites via a non-nuclear mechanism.
Authors:Pin S, Chen H, Lein PJ, Wang MM
Journal:J Neurochem
PubMed ID:16441515
'The mechanism by which drugs that target nucleic acids cause neurotoxicity is not well described. We characterized the neurotoxicity of Hoechst 33342 (bis-benzimide), a common cell permeable nuclear dye, in primary neuronal cultures. The mechanism of cell death was not apoptotic, as death is rapid, not accompanied by typical nuclear ... More
Multiparameter detection of apoptosis using red-excitable SYTO probes.
'Functional assays allowing phenotypic characterization of different cell death parameters at a single-cell level are important tools for preclinical anticancer drug screening. Currently, the selection of cytometric assays is limited by the availability of fluorescent probes with overlapping spectral characteristics. Following on our earlier reports on green and orange fluorescent ... More
Liver fatty acid-binding protein colocalizes with peroxisome proliferator activated receptor alpha and enhances ligand distribution to nuclei of living cells.
Authors:Huang H, Starodub O, McIntosh A, Atshaves BP, Woldegiorgis G, Kier AB, Schroeder F
Journal:Biochemistry
PubMed ID:14992586
'Although it is hypothesized that long-chain fatty acyl CoAs (LCFA-CoAs) and long-chain fatty acids (LCFAs) regulate transcription in the nucleus, little is known regarding factors that determine the distribution of these ligands to nuclei of living cells. Immunofluorescence colocalization showed that liver fatty acid-binding protein (L-FABP; binds LCFA-CoA as well ... More
Cytoplasmic and nuclear delivery of a TAT-derived peptide and a beta-peptide after endocytic uptake into HeLa cells.
Authors:Potocky TB, Menon AK, Gellman SH
Journal:J Biol Chem
PubMed ID:14517218
'Several short, highly cationic peptides are able to enter the cytoplasm and nucleus of cells from the extracellular medium. The mechanism of entry is unknown. A number of fluorescence-based studies suggested that these molecules cross the plasma membrane by an energy-independent process, directly gaining access to the cytoplasm. Recent reports ... More
