  • TROUBLESHOOTING SODIUM DODECYL SULFATE-

    2009-5-25 · The denaturing gel induces melting of the DNA at various stages. As a result of this melting, the DNA spreads through the gel and can be analyzed for single components. DGGE (Muyzer et al. 1993) analyses are employed for the separation of double-stranded DNA fragments that are identical in length, but differ in sequence.

  • Running agarose and polyacrylamide gels

    2011-6-17 · The basics. Agarose gels can be used to resolve large fragments of DNA. Polyacrylamide gels are used to separate shorter nucleic acids, generally in the range of 1−1000 base pairs, based on the concentration used (Figure 1). These gels can be run with or without a denaturant. Gels that are run without a denaturant are referred to as native gels.
