20 Φεβ 2018 · Gel electrophoresis is the standard lab procedure for separating DNA by size (e.g., length in base pairs) for visualization and purification. Electrophoresis uses an electrical field to move the negatively charged DNA through an agarose gel matrix toward a positive electrode.
Agarose gel electrophoresis has proven to be an efficient and effective way of separating nucleic acids. Agarose's high gel strength allows for the handling of low percentage gels for the separation of large DNA fragments.
Agarose Gel Preparation Protocol. Introduction. Agarose gels are a standard component of gel electrophoresis, an effective technique used in the separation and analysis of deoxyribonucleic acid (DNA) fragments. Agarose is a polysaccharide composed of agar (agarobiose), a natural product of seaweed.
Protocol. Alkaline Agarose Gel Electrophoresis. Michael R. Green and. Joseph Sambrook. Abstract. Alkaline agarose gels are run at high pH, which causes each thymine and guanine residue to lose a proton and thus prevents the formation of hydrogen bonds with their adenine and cytosine partners.
This protocol describes steps for the preparation and running of agarose gels and for staining and visualization of DNA in gels using three dyes: ethidium bromide, SYBR Gold, and SYBR Green 1.
We have divided each protocol into four basic steps: (1) preparing and pouring the agarose gel; (2) preparing and loading samples; (3) running the agarose gel; and (4) staining the gel using the fluorescent stain ethidium bromide to visualize DNA and RNA. © 2015 by John Wiley & Sons, Inc.

Gel purification allows you to isolate and purify DNA fragments based on size. The procedure starts with standard agarose gel electrophoresis, which separates DNA by their length in base pairs. Following electrophoresis, you can cut DNA bands out of the agarose gel and purify the DNA samples.
