DNA Polyacrylamide Gel Electrophoresis - UC Davis
How to pour and run a neutral polyacrylamide gel. Ammonium persulfate is used as a catalyst for the copolymerization of acrylamide and bisacrylamide gels. The polymerization reaction is driven by free radicals that are generated by an oxido-reduction reaction in which a diamine (e.g., TEMED) is used as the adjunct catalyst.

The purified fragments can then be used for cloning, sequencing,or labeling. The protocols in this unit outline pouring and electrophoresisof nondenaturing polyacrylamide gels.
What voltage does a nondenaturing polyacrylamide gel run at?
Nondenaturing polyacrylamide gels are usually run at voltages between 1 V/cm and 8 V/cm. If electrophoresis is carried out at a higher voltage, differential heating in the center of the gel may cause bowing of the DNA bands or even melting of the strands of small DNA fragments.
What is polyacrylamidegel electrophoresis (PAGE)?
BackgroundInformation Polyacrylamidegel electrophoresis (PAGE) offers high resolution of low-molecular-weightnucleic acids. In particular, small DNA fragments (<500 bp) that arepoorly resolved by ordinary agarose gels are easily separated on polyacrylamidegels.
