Compositions and methods for improving sample identification in indexed nucleic acid libraries

Abstract:

The present invention is concerned with compositions and methods for improving the rate of correct sample identification in indexed nucleic acid library preparations for multiplex next generation sequencing by modifying or blocking 5' and 3' ends of pooled indexed polynucleotides from multiple samples, with an optional exonuclease treatment, prior to amplification and sequencing.
