1. A method of attaching a polynucleotide to a surface comprising:
- (a) generating a hydrophilic compartment of an inverse emulsion comprising a polynucleotide and a surface, wherein said polynucleotide comprises a photoactivatable binding moiety and said surface comprises a binding moiety binding partner; and
(b) exposing said hydrophilic compartment to activating electromagnetic radiation to activate said photoactivatable binding moiety to bind said binding partner thereby attaching said polynucleotide to said surface.

Abstract
Compositions and methods of use are disclosed for clonally amplifying target polynucleotide sequences in solution and attaching the amplicons to a surface by activation of a masked binding moiety. In an embodiment, the amplicons comprise the masked binding moiety and the surface comprises a binding partner of the binding moiety. Upon activation of the binding moiety, the amplicons bind to the binding partner on the surface. In a non-limiting example, the masked binding moiety is caged biotin or caged fluorescein, while the corresponding binding partner is avidin or an anti-fluorescein antibody.

13. A method of attaching an amplicon to a bead comprising:
-
(a) amplifying a template polynucleotide in a hydrophilic compartment of an inverse emulsion to produce an amplicon, wherein the hydrophilic compartment comprises a template polynucleotide, a surface and reagents suitable for polynucleotide amplification, wherein said amplicon comprises a photoactivatable binding moiety and said surface comprises a binding moiety binding partner; and (b) activating said photoactivatable binding moiety by exposing said compartment to activating electromagnetic radiation to activate said binding moiety to bind said binding partner thereby attaching said amplicon to said surface. - View Dependent Claims (14, 15, 16, 17)
