Description:
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.
Physical Properties:
Off-white/white solid or viscous liquid depends on molecule weight;
Soluble in regular aqeous solution as well as most organic solvents;
COOH-PEG-SIL，羧基PEG硅烷，硅烷聚乙二醇羧基 Storage Conditions:
Store at -20 0C, desiccated. Silane PEG tends to hydrolyze from moisture. Avoid frequent thaw and frozen.
Reaction Procedures:
Generally, silane PEG is first dissolved in a mixture of ethanol/water solution, then allow the solution to contact with oxidized glass or silica surface for 30 min to 2 hours. Under this condition, silane PEG should bind to the material covalently.
Materials Required:
Pegylation solution: Ethanol/water (w/w, 95%/5%);
Silane PEG stock solution, 10~50 mg/mL in pegylation solution, prepare in fresh.
Washing solution: Distilled water.
Reaction Steps:
1. Dissolve targeted materials in Pegylation buffer.
2. Add silane PEG stock solution to the targeted conjugation materials with the final concentration keep at least 10 mg/mL. 10~50 molar excess of silane PEG needed for optimal conjugation;
3. Allow mixture agitates at room temperature for 30 min at room temperature or 2 hours at 4 -20 0C.
4. Wash out unreacted materials either by distilled water.
