| 摘要 |
The presently claimed invention provides for novel methods and kits for reducing the complexity of a nucleic acid sample by providing non-gel based methods for size fractionation. In a preferred embodiment, size fractionation can be accomplished by varying conditions or reagents of a PCR reaction to amplify fragments of specific size ranges. The invention further provides for analysis of the above sample by hybridization to an array, which may be specifically designed to interrogate the desired fragments for particular characteristics, such as, for example, the presence or absence of a polymorphism.
