Patent Images
1. A support for the solid phase amplification or sequencing of nucleic acids comprising:
- a polyfunctionalized solid support;
a linker having a multiplicity of functional groups capable of binding to said solid support; and
an oligonucleotide primer bound at a 5′
end to said linker;
wherein said primer is immobilized on said solid support via said linker by means of at least one covalent bond between said functional groups and said solid support.

Abstract
A support for solid phase amplification or sequencing of nucleic acids has a functionalized solid support, a linker arm having functional groups covalently bound to the solid support through at least one binding site of the functional groups, and an oligonucleotide primer bound at its 5′ end to the linker, the primer, thereby, being immobilized on the solid support.
