Abstract

During modification of protein amino groups with carboxylic acid anhydrides, these reagents cause a fall in pH, which can be prevented by addition of base. Although unmodified nucleosomal particles are not affected by the local transient changes in pH induced by the base (NaOH) added to prevent a fall in pH during modification, the nucleosomal particles modified by acetic anhydride are dissociated, with release of single-stranded DNA.

摘要

在用羧酸酐修饰蛋白质氨基的过程中，这些试剂会导致pH值下降，可通过添加碱来防止这种情况。虽然未修饰的核小体颗粒不受为防止修饰过程中pH值下降而添加的碱（NaOH）引起的局部短暂pH值变化的影响，但经乙酸酐修饰的核小体颗粒会发生解离，并释放出单链DNA。
