Ethoxy or methoxyl silane functionalized polyethylene glycol, silane PEG (PEG-Si) is a surface reactive PEG derivative that can be used to modify glass, silica and other surfaces via the reaction between hydroxyl group and ethoxyl/methoxyl silane. Pegylation can greatly suppress the non-specific binding of charged molecules to the modified surfaces. And they have wide applications for medica device, biomems or biocompatible material development.

一般来说,先将硅烷 PEG 溶解在乙醇/水的混合溶液中,然后让溶液与氧化玻璃或二氧化硅表面接触 30 分钟至 2 小时。在此条件下,硅烷 PEG 应与材料共价结合。
所需材料
反应步骤: 1:
1.将目标材料溶解于聚乙二醇化缓冲液中
。 2. 向目标共轭材料中加入硅烷 PEG 原液,最终浓度至少为 10 mg/mL。硅烷 PEG 的摩尔过量为 10~50,才能达到最佳共轭效果;
3. 让混合物在室温下搅拌 30 分钟,或在 4 -200C下搅拌 2 小时。
4.用蒸馏水洗去未反应的物质。
