Method for constructing an oligonucleotide concatamer library by rolling circle replication
First Claim
1. An in vitro method for constructing an oligonucleotide concatamer library, comprising the steps of:
- a) generating a population of primer-bridged circular template oligonucleotides by annealing linear primer oligonucleotides to linear template oligonucleotides and ligating said linear template oligonucleotides into circular template oligonucleotides;
b) generating a population of single-stranded oligonucleotide concatamers by rolling circle replication of said primer-bridged circular template oligonucleotides; and
c) generating a population of corresponding double-stranded oligonucleotide concatamers by synthesizing single stranded oligonucleotides which are complementary to said population of single-stranded oligonucleotide concatamers.

Abstract
An in vitro method for constructing an oligonucleotide concatamer library is revealed. The method has four steps. The first step involves the generation of a primer-bridged circular template oligonucleotide. In the second step, the primer-bridged circular template is used to generate a single-stranded oligonucleotide concatamer by rolling circle replication. In the third step, the single-stranded oligonucleotide concatamer is converted to a double-stranded oligonucleotide concatamer. Finally, the double-stranded oligonucleotide concatamer is cloned or used directly in in vitro assays which allow molecules of interest to be isolated or amplified.
