Separation of Histone Variants and Post‐Translationally Modified Isoforms by Triton/Acetic Acid/Urea Polyacrylamide Gel Electrophoresis

Due to their similarities in size and charge, complete resolution of histones by electrophoresis poses a considerable challenge. The addition of nonionic detergents to the traditional acetic acid/urea (AU) polyacrylamide gel electrophoresis (PAGE) system has afforded

多肽的基本常识

：（略） 基于保护基团的类别，必须使用去保护剂的组合。 例如， 当Boc和tButyl存在时，它们的Carbocation对应物能与Trp, Tyr和Met反应形成tbutyl产物。EDT是极有效的t-butyl trifluoroacetate清除剂， 但它不保护Trp。 因此，必须加水以控制烷基化。Trp的吲哚环和Tyr的OH极易与Pmc反应。水再次表现出对此反应的抑制。Trt和Mtr基团也有相似情形。较此适当组合清除剂将极大降低副反应。 tBoc和CBZ多肽合成
