Methods for constructing in vitro fragment libraries. (a) In the conventional protocol, mechanical or endonuclease fragmentation is followed by end-polishing, A-tailing, adaptor ligation and PCR. (b) With transposase-mediated adaptor insertion, fragmentation and adaptor insertion occur in a single 5-min in vitro step, followed by PCR. For both methods, a primer-embedded sample-specific barcode can be incorporated during PCR amplification (black triangle).
