anionic polyacrylamide gradient gel electrophoresis features

  • Polyacrylamide temperature gradient gel

    Temperature Gradient Gel Electrophoresis (TGGE) is a form of electrophoresis in which temperature gradient is used to denature molecules as they move through either acrylamide or agarose gel. TGGE can be applied to analyze DNA, RNA, protein-DNA complexes, and, less commonly, proteins. Separation of double-stranded DNA molecules during TGGE relies on temperature-dependent melting of the DNA ...

  • Polyacrylamide Gel Electrophoresis - an overview ...

    Studying proteins requires the ability to isolate and identify the proteins in a particular sample. The first step is to separate them by size. Much as electrophoresis on agarose gels is used to separate DNA fragments by size, so polyacrylamide gel electrophoresis (PAGE) is used to separate proteins by size (Fig. 9.1). Polyacrylamide has smaller pores than agarose and is thus suitable for proteins because …
