Method for processing a library using ligation inhibition

摘要

An objective of this invention is to provide a method which can specifically enrich a desired DNA with a long insert size from a DNA library and can provide a clone of the DNA directly. This invention provides a method of constructing a DNA library having increased proportion of a first double-stranded DNA therein by removing, from an original library containing the first double-stranded DNA to be increased in proportion, a second double-stranded DNA different from the first double-stranded DNA. <IMAGE>
