  • Polyacrylamide Gel Electrophoresis of RNA

    There are two common types of gel: polyacrylamide and agarose. For most applications, denaturing acrylamide gels are most appropriate. These gels are extremely versatile and can resolve RNAs from ~600 to ≤20 nucleotides (nt). In certain circumstances, e.g., resolving different conformers of RNAs or RNA-protein complexes, native gels are ...

    Similarly, addition of a phosphate moiety decreases the net positive charge of the protein during gel electrophoresis by one. Separation between similarly sized and charged proteins, for example, the partially acetylated H2A, H2B, and H3 histones of most organisms, can typically be achieved only by inclusion of a nonionic detergent such as Triton X-100 ( see Chapter 17 ).

    Zweidler discovered that core histones but not linker histones (see Note 1) bind the nonionic detergent Triton (1). Generally, Triton is added to an acetic acid-urea (AU) gel system to separate core histone sequence variants and histone species with overlapping AU gel patterns. This type of gel is known as an AUT or a TAU gel.
