[摘要]:An alkanethiol spacer which is suitable for biointerface was synthesized on 2-chlorotritylchloride (CTC) resin using solid-phase synthesis method. The triethylene glycol (TEG) unit containing building block was immobilized on CTC resin followed by a coupling alkanethiol building block. After dithiothreitol (DTT) treatment and cleavage of the resulting alkanethiol spacer from the resin, the spacer was obtained in a pure form without any purification steps. The TEG-alkanethiol spacer was applied for the DNA hybridization assay on a gold surface, and proved to work well when compared to the commercial spacer. |
