  • Denaturing polyacrylamide gel electrophoresis

    Abstract. Polyacrylamide gels that contain a high concentration of urea as a denaturant are capable of resolving short (<500 nucleotides) single-stranded fragments of DNA or RNA that differ in length by as little as one nucleotide. Such gels are commonly used for DNA sequence analysis, as well as in PCR amplification of SSLPs (simple sequence ...

Polyacrylamide gel electrophoresis (PAGE) remains one of the best tools for the purification of oligos and nucleic acids in general (RNA and other second/third generation molecules, e.g. LNA’s, UNA’s, etc). The 7M urea ensures the linearity of the nucleic acids, by avoiding secondary/tertiary structure formation. 0.1% APS ...

  • Denaturing urea polyacrylamide gel electrophoresis

    Urea PAGE or denaturing urea polyacrylamide gel electrophoresis employs 6-8 M urea, which denatures secondary DNA or RNA structures and is used for their separation in a polyacrylamide gel matrix based on the molecular weight. Fragments between 2 to 500 bases, with length differences as small as a single nucleotide, can be separated using this method(1).

    CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Polyacrylamide gel electrophoresis techniques performed in constant (CDGE) or gradient (DGGE) denaturing gels that are commonly used to detect DNA mutations were adapted for the detection of mutations directly in dsRNA molecules. The techniques were applied to investigate genomic differences between a highly ...

    2019-5-27 · one modified non-denaturing gel electrophoresis methods for analysis of total RNA extracted from SiHa cells. We consistently and repeatedly found that RNA separation on non-denaturing gel was better than denaturing gel electrophoresis in terms of intensity and integrity of 28S and 18S rRNA bands.
