Method of making an array of nucleic acid colonies

Abstract

A method of making an array of nucleic acid colonies, by (a) providing a substrate having a patterned surface of features, wherein the features are spatially separated from each other on the surface of the substrate; (b) contacting the substrate with a solution of different target nucleic acids to seed a subset of the features that contact the solution, wherein each feature in the subset is seeded with a single nucleic acid from the solution, wherein a plurality of the features that contact the solution are not seeded with a nucleic acid from the solution; (c) amplifying the nucleic acids to form a nucleic acid colony at each of the features in the subset; and (d) repeating steps (b) and (c) to increase the number of the features on the surface that have a nucleic acid colony, thereby making an array of nucleic acid colonies.
