一般描述

这种氮杂二苯并环辛-生物素衍生物是一种通用的生物素化试剂，用于标记含有叠氮化物的分子或化合物。环辛烯在促进无铜叠氮炔环加成反应中是有用的。这种二苯并环辛炔将与叠氮官能化化合物或生物分子反应，而不需要 Cu (I) 催化剂产生稳定的三唑键。后续的标记分子可以使用链霉亲和素或亲和素亲和试剂进行纯化。PEG 间隔基使整体化合物的亲水性更强，并允许与叠氮化物的反应站点和生物素检测基团之间的距离更大。

应用

采用 Synple 自动合成平台素（SYNPLE-SC002）自动标记生物素

特点和优势

更高的温度和过多的生物素试剂会导致更有效的标记。典型反应时间长达 4 小时，但如果浓度较低或观察到低标记，则应使用更长的孵育时间。当首先溶解在水溶性有机溶剂中，然后根据需要在水性反应缓冲液中稀释时，产品最有效。DBCO-PEG4-生物素可溶于高达 0.35 mM 的水性缓冲液。

Polyunsaturated fatty acids (PUFA) are primary targets of free radical damage during oxidative stress. Diffusible electrophilic alpha,beta-unsaturated aldehydes, such as 4-hydroxynonenal (HNE), have been shown to modify proteins that mediate cell signaling (e.g., IKK and Keap1) and alter gene expression

Fatty-acylation of proteins in eukaryotes is associated with many fundamental cellular processes but has been challenging to study due to limited tools for rapid and robust detection of protein fatty-acylation in cells. The development of azido-fatty acids enabled the nonradioactive
