一般描述
与包含不同 PEG 链长的非均匀混合物的典型 PEG 试剂相比,该 PEG 试剂是具有确定的分子量和间隔臂长的均质化合物,在优化和表征交联应用方面提供了更高的精度。
应用
BS(PEG)9可作为交联剂用于:
- 研究鲍曼不动杆菌生物膜形成调节因子BfmR的结构域结构。
- 研究视觉兴奋机制。
特点和优势
- 反应基团:磺基-NHS酯(两端)
- 反应性:氨基(伯胺)
- 在 pH 7-9 下,NHS 酯与 -NH2 基反应形成稳定的酰胺键
- 水溶性;与非聚乙二醇化的 Bs3(也可溶)和 DSS(不溶于水)进行比较
- 不可透过膜,允许细胞表面标记
- 通过柔性PEG间隔臂不可逆地交联蛋白质或肽
- 聚乙二醇间隔臂有助于保持偶联物溶解度
- 具有确定结构和分子量的纯化合物,确保可重复的蛋白质修饰效果
- PEG间隔臂提供独特的优势,包括增加稳定性、降低聚集倾向和降低免疫原性
- 非常适合小分子或肽结合
注意
这种产品对湿气很敏感。小瓶包装在带有干燥剂的可再密封袋中,以减少湿气接触。冷藏后,打开前将小瓶平衡至室温,以减少小瓶内的冷凝。制备新的溶液。不建议储存原液。使用后,将小瓶放回可重新密封的袋子中。封闭袋子,在推荐的温度下储存产品。
