www.nacalai.co.jpGel-based methods of purification, such as preparative denaturing polyacrylamide gel electrophoresis (PAGE) and agarose gels, are limited by poor resolution of RNA size and potential chemical modifications from reagents such as formaldehyde. To date, high performance liquid chromatography (HPLC) remains a staple method for purification of
Appendix A: Electrophoretic Theory
www.lonzabio.jpElectrophoresis is defined as the movement of ions and charged macromolecules through a medium when an electric current is applied. Agarose and polyacrylamide are the primary stabilizing media used in the electrophoresis of macromolecules. Macromolecules are separated through the matrix based on size, charge distribution and structure.
