Protection of DNA during preparative agarose gel electrophoresis against damage induced by ultraviolet light.
Preparative gel electrophoresis of double-stranded DNA usually includes staining the gel with ethidium bromide followed by illumination with ultraviolet (UV-B) light. In this report, DNA isolated from agarose gels was found to be a poor substrate for in vitro transcription, transformation of E. coli and PCR. Inhibition was not caused by enzyme-inhibiting impurities in the agarose gel, but was i...
متن کاملAssessment of DNA damage induced by butachlor on Cyprinuscarpio(L. 1758) using Single Cell Gel Electrophoresis
Butachlor (N-(butoxymethyl)-2-chloro-N-2, 6-diethylacetanillide) is widely used chloroacetanilide herbicide in Asian region, especially in the north of Iran. Several studies have been reported on toxicity of butachlor, but little information is accessible on DNA damaging potential. Thus, the present study was undertaken to investigate of DNA damage by butachlor in Cyprinuscarpio(Pisces: Cyprini...
متن کاملTrapping of megabase-sized DNA molecules during agarose gel electrophoresis.
Megabase DNA molecules become trapped in agarose gels during electrophoresis if the electric field exceeds a few volts per cm. Fluorescence microscopy reveals that these molecules invariably arrest in U-shaped conformations. The field-vs.-size dependence for trapping indicates that a critical molecular tension is required for trapping. The size of unligated lambda-ladders, sheared during gel el...
متن کاملContinuous preparative gel electrophoresis.
Electrophoresis is widely used as a separative technique, particularly in protein chemistry. In some respects gelatinous media have an advantage over others as support media for electrophoresis, perhaps most obviously when a gel matrix of molecular dimensions is employed, allowing the simultaneous use of two properties for separation of the particles of interest-size and surface charge density....
متن کاملAgarose gel electrophoresis.
MATERIALS 6x Gel-loading buffer Agarose solutions (please see Step 3) DNA samples DNA size standards Samples of DNAs of known size are typically generated by restriction enzyme digestion of a plasmid or bacteriophage DNA of known sequence. Alternatively, they are produced by ligating a monomer DNA fragment of known size into a ladder of polymeric forms. DNA staining solution For a discussion of...
