Abstract

A novel linker for the synthesis of oligonucleotides on a glass support is described. Oligonucleotides synthesised on the support remain tethered to the support after ammonia treatment and are shown to take part in sequence specific hybridisation reactions. These hybridizations were carried out with oligonucleotides synthesised on 'ballotini' solid sphere glass beads and microscope slides. The linker has a hexaethylene glycol spacer, bound to the glass via a glycidoxypropyl silane, terminating in a primary hydroxyl group that serves as starting point for automated or manual oligonucleotide synthesis.
