Background Trevigen’s CometAssay®, or single cell gel electrophoresis assay, provides a simple and effective method for evaluating DNA damage in cells. The principle of the assay is based upon the ability of denatured, cleaved DNA fragments to migrate out of the nucleoid under the influence of an electric field, whereas undamaged DNA migrates slower and remains within the confines of the nucleoid when a current is applied. Evaluation of the DNA “comet” tail shape and migration pattern allows for assessment of DNA damage.

However, its suitability for epifluorescence microscopy has not been sufficiently investigated. Thus we compared bacterial and viral counts using SYBR Gold and SYBR Green I stains. Variables for both bacterial and viral counts included season and ocean depths of sample collection and the period of sustained excitation under epifluorescence microscopy. We also examined the storage period and procedures for preservation of samples with formaldehyde for bacterial counts. Natural seawater samples were used for all experiments. Ratios of counts obtained with SYBR Gold to those with SYBR Green I staining were 0.99 ± 0.09 (mean ± SD, n = 58) for bacteria and 1.0 ± 0.1 (n = 38) for viruses, which indicated no significant differences between stains. In samples fixed with 0.74% formalde- hyde that were stored at 4°C, bacterial counts obtained with SYBR Gold staining decreased over time in parallel with those obtained with SYBR Green I staining.

Abstract We describe a method to analyze the affinity and specificity of interactions between proteins and RNA using horizontal PAGE under non-denaturing conditions. The method permits tracking of migration of anionic and cationic biomolecules and complexes toward anode and cathode, respectively, therefore enabling quantification of bound and free biomolecules of different charges and affinity of their intermolecular interactions. The gel is stained with a fluorescent intercalating dye (SYBR®Gold or ethidium bromide) for visualization of nucleic acids followed by Coomassie® Brilliant Blue R-250 for visualizations of proteins; the dissociation constant is determined separately from the intensity of unshifted and shifted bands visualized by each dye.

  • SYBR Gold Nucleic Acid Gel Stain
    SYBR® Gold Nucleic Acid Gel Stain Table 1. Contents and storage information. Material Amount Concentration Storage Stability • ≤–20°C When stored as directed, Solution in high-quality, SYBR® Gold nucleic acid gel stain 500 µL • Desiccate stain stock solution is stable anhydrous DMSO * • Protect from light for 6 months to 1 year. * DMSO stock solution is a 10,000X concentrate. Number of labelings: Sufficient dye is provided to stain at least 100 agarose or polyacrylamide minigels. Approximate fluorescence excitation/emission maxima: 300, 495/537 nm, bound to nucleic acid Introduction Molecular Probes SYBR® Gold nucleic acid gel stain is the most sensitive fluorescent stain available for detecting double- or single-stranded DNA or RNA in electrophoretic gels, using standard ultraviolet transilluminators—surpassing even the sensitivity of our SYBR® Green gel stains in this application.1 SYBR® Gold stain is a proprietary unsymmetrical cyanine dye that ex­hibits >1000-fold fluorescence enhancement upon binding to nucleic acids and has a high quantum yield (~0.6) upon binding to double- or single-stranded DNA or to RNA.1 Ex­citation max­ima for dye–nucleic acid complex­es are at ~495 nm in the visible and ~300 nm, in the ultraviolet (Figure 1). The emission max­imum is ~537 nm. SYBR® Gold stain is >10-fold more sensitive than ethidium bromide for detecting DNA and RNA in denaturing urea, glyox­al, and formaldehyde gels, even with 300 nm transillumination.1 For detecting glyox­alated RNA, SYBR® Gold stain is 25–100 times more sensitive than ethidium bromide (Figure 2) and is by far the most sensitive stain available for this application.1 SYBR® Gold stain has also been shown to be much more sensitive than SYBR® Green II stain for detecting single strand con- formation polymorphism (SSCP) products.2 SYBR® Gold stain penetrates thick and high per- centage agarose gels rapidly, and even formaldehyde agarose gels do not require destaining, due to the low intrinsic fluorescence of the unbound dye.

  • Alternatives to Ethidium Bromide
    Alternatives to Ethidium Bromide Ethidium Bromide Ethidium Bromide has been used as a stain to visualise nucleic acids in agarose and polyacrylamide gels because of its high sensitivity and rapid action. Due to its ability to enter into DNA /RNA chains it is now regarded as a possible mutagen and / or carcinogen and its use is decreasing in certain establishments. Alternatives and Risk Assessment There are several alternative nucleic acid stains available from a variety of manufacturers. The use of these dyes should be considered during the project risk assessment as any chemical which can react with nucleic acids could potentially act as a mutagen. Some stains have been evaluated using the Ames I and / or the Ames II tests, however it should be borne in mind that these tests are in vitro and it is possible that they may exert mutagenic effects. It is good practice to prevent pregnant women working in laboratories where DNA / RNA stains are being used. When undertaking the risk assessment the hierarchy of control is to eliminate the chemical if possible, substitute it for a less hazardous chemical, reduce the length of exposure to the chemical, or consider a means of enclosing the process and using suitable gloves or goggles. It is also advisable to consider the effects of the light that is used to visualise the stained gel and also the disposal procedures when completing the risk assessment and SOP. It should be borne in mind that any product that is capable of interacting with nucleic acids in vivo may be capable of causing genetic damage and it is best to avoid contact by wearing gloves as appropriate.

  • Virus and Prokaryote Enumeration from Planktonic Aquatic Environments by Epifluorescence Microscopy with SYBR Green I Anand

Correspondence should be addressed to A.P. ([email protected]). Published online XX Month 2007; doi:10.1039/nprot.2007.006 Viruses are the most abundant biological entities in aquatic environments, typically exceeding the abundance of bacteria by an order of magnitude. The reliable enumeration of virus-like particles in marine microbiological investigations is a key measurement parameter. Although the size of typical marine viruses (20–200 nm) is too small to permit the resolution of details by light microscopy, such viruses can be visualized by epifluorescence microscopy if stained brightly. This can be achieved using the sensitive DNA dye SYBR Green I (Molecular Probes–Invitrogen). The method relies on simple vacuum filtration to capture viruses on a 0.02-!m aluminum oxide filter, and subsequent staining and mounting to prepare slides. Virus-like particles are brightly stained and easily observed for enumeration, and prokaryotic cells can easily be counted on the same slides. The protocol provides an inexpensive, rapid (30 min) and reliable technique for obtaining counts of viruses and prokaryotes simultaneously.

Marei B.S. University of Cincinnati June 2006 Committee Chair: Pearl Tsang, Ph.D. Abstract A method for production of milligrams of hKtRNA, using new template plasmid pLysB19, by in vitro transcription is presented and compared to methods in use elsewhere. The in vitro transcription yield was found to be almost exclusively dependent on Mg2+ and template concentration. Currently, production of milligrams of hKtRNA is possible but only by use of higher template concentrations than reported elsewhere (7μg vs.
