DNAet er usynlig for det blotte øyet og man bruker derfor etidiumbromid (EtBr)for å visualisere DNAet. Stoffet binder seg mellom baseparene i DNAet og med UV-lys kan man se DNAet, andre fargestoff brukes òg. Det finnes to hovedtyper av gelmateriale som brukes ved separasjon av DNA: polyakrylamid og agarose. Både agarose och akrylamid. Färgen fluorescerar intensivt endast då den är bunden till nukleinsyra vilket ger en låg bakgrundsinfärgning och möjliggör att ingen avfärgning behövs vid post staining. GelStar rekommenderas ej att tillsättas vid gjutning av vertikala geler, utan då ska de post-stainas. In-gel staining och post-gel AGE/EBS står för Agaros Gel elektrofores med etidiumbromid färgning.

At higher concentrations (0,5 to 1,0 μg/ml), it may be used to facilitate purification of DNA in a caesium chloride gradient. One drop diluted into 50 ml of molten agarose or buffer yields a final concentration of 0.5 μg/ml. Effect of adding ethidium bromide (EtBr) directly to an agarose gel.

Alternative stains for DNA in agarose gels include SYBR Gold, SYBR green, crystal violet and methyl blue. The sensitivities of methylene blue and crystal violet are low compared with ethidium bromide.

Sammanställning över alternativ till etidiumbromid

EtBr binds to the DNA and allows you to visualize the DNA under ultraviolet (UV) light. The agarose gel will have to be post stained after electrophoresis. The most commonly used stain for visualizing DNA is ethidium bromide (EtBr)*. Alternative stains for DNA in agarose gels include SYBR Gold, SYBR green, crystal violet and methyl blue. The sensitivities of methylene blue and crystal violet are low compared with ethidium bromide. Agarose is made up of polysaccharides and is commonly used in laboratories for the purpose of agarose gel electrophoresis for the separation of DNA and other polynucleotides.
