Thermo Scientific Pierce EGS 是一种交联剂,含有位于 12原子间隔臂周围的胺反应性 NHS 酯末端,其可通过在 pH 值 8.5 时使用羟胺处理进行裂解。

EGS 交联剂的特点:

反应性基团:NHS 酯(两端)
可与以下基团发生反应:氨基(伯胺)
•不溶于水(首先溶于 DMF 或 DMSO);与 Sulfo-EGS 具有可比性
•膜可透过性,可进行细胞内交联
•在 pH 值为 8.5 时于 37°C 下使用羟胺处理持续 3 至 6 小时,形成的交联是可逆的
• 乳糖脱氢酶在与 EGS 可逆交联后保持 60% 的活性

Can NHS-diazirine (Cat. No. 26167) be used for CHIP applications?

NHS-diazirine has not been tested for cross-linking in a ChIP application. EGS (Cat. No. 21565) and DSG (Cat. No. 20593) are not used by themselves in ChIP, but rather in combination with formaldehyde. While formaldehyde is good for crosslinking proteins that are in direct contact with DNA, it cannot trap proteins that may be bound in a complex with other proteins but are not in direct contact. Thus EGS or DSG can cross-link proteins to proteins that are in direct contact with DNA and are crosslinked to it by formaldehyde. See this reference for more information
