Acid-Urea-Triton Polyacrylamide Gel Electrophoresis of …
Acid-urea polyacrylamide gels are capable of separating basic histone proteins provided they differ sufficiently in size and/or effective charge (see Chapter 16). Separation between similarly sized and charged molecules, such as the histones H2A, H2B, and the H3 forms of most organisms, can typically not be achieved.
Acid-Urea-Triton Polyacrylamide Gel Electrophoresis of Histones
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.
Acid-Urea-Triton Polyacrylamide Gel Electrophoresis of Histones
In addition, a detailed working protocol for a long acid-urea-Triton (AUT) gel at 9 m M Triton and 8 M urea is provided. It describes the protocol used extensively in my laboratory for the analysis of core histones, especially of histone H3, dicots (6), monocots (7), and the green alga Chlamydomonas (8).

AU gels are currently used for very dissimilar proteins with isoelectric points lower than those of histones but sufficiently above pH 3 to be positively charged during gel electrophoresis. Examples include neutrophil defensins (), antimicrobiol nasal secretions (), enzymes like tyrosinase (), serum isoenzymes (), chemokines and basic protamines ().

Triton acid-urea gels were prepared by pipetting 5 mL of resolving gel in 10 cm × 10.5 cm × 0.075 cm assembly with a gel mixture prepared as described in Table 2. Gels were layered with 1 mL water and allowed to polymerize for 20 minutes at room temperature. 2 mL of stacking gel solution were formulated as shown in Table 2 and layered on top of the resolving gel.
Acid-Urea-Triton Polyacrylamide Gels for Histones
Acid-urea polyacrylamide gels are capable of separating basic histone proteins provided they differ sufficiently in size and/or effective charge (see Chapter 14). Separation between similarly sized and charged H2A, H2B, and H3 forms of most organisms can
