The presently claimed invention provides methods and kits for amplifying a target sequence from within a nucleic acid population. The presently claimed invention provides selection probes which are complementary to at least a portion of said target sequence and mechanisms for adding a probe sequence to the 3' end of a target sequence that is hybridized to a selection probe. The added 3' probe sequence and a probe sequence added at the 5' end of the target by adaptor ligation allow for selective amplification of the target sequence.
