The cell-permeant SYTO 63 red fluorescent nucleic acid stain exhibits bright, red fluorescence upon binding to nucleic acids. Because the staining pattern of the SYTO dyes in live cells may vary between cell types, we offer the SYTO Red Fluorescent Nucleic Acid Stain Sampler Kit (Cat. No. S-11340) to enable researchers to find the most appropriate red-fluorescent SYTO stain for their system.

Any physiological buffer between pH 7.0–8.0, including PBS, can be used to dilute the SYTO dyes for the staining solution.

For Research Use Only. Not for use in diagnostic procedures.

Frequently asked questions (FAQs)

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.

Abstract

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.

Authors:Wlodkowic D, Skommer J, Hillier C, Darzynkiewicz Z,

Journal:Cytometry A

PubMed ID:18431792

'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

Differentiation of Phytophthora infestans sporangia from other airborne biological particles by flow cytometry.

Authors:Day JP, Kell DB, Griffith GW

Journal:Appl Environ Microbiol

PubMed ID:11772606

'The ability of two different flow cytometers, the Microcyte (Optoflow) and the PAS-III (Partec), to differentiate sporangia of the late-blight pathogen Phytophthora infestans from other potential airborne particles was compared. With the PAS-III, light scatter and intrinsic fluorescence parameters could be used to differentiate sporangia from conidia of Alternaria or ... More

High throughput single molecule detection for monitoring biochemical reactions.

Authors:Okagbare PI, Soper SA,

Journal:Analyst

PubMed ID:19082181

The design, performance and application of a novel optical system for high throughput single molecule detection (SMD) configured in a continuous flow format using microfluidics is reported. The system consisted of a microfabricated polymer-based multi-channel fluidic network situated within the optical path of a laser source (lambda(ex) = 660 nm) ... More

Cytoplasmic O-glycosylation prevents cell surface transport of E-cadherin during apoptosis.

Authors:Zhu W, Leber B, Andrews DW

Journal:EMBO J

PubMed ID:11689440

Cellular adhesion is regulated by members of the cadherin family of adhesion receptors and their cytoplasmic adaptor proteins, the catenins. Adhesion complexes are regulated by recycling from the plasma membrane and proteolysis during apoptosis. We report that in MCF-7, MDA-MB-468 and MDCK cells, induction of apoptosis by agents that cause ... More
