6 Methods to Fragment Your DNA / RNA for Next-Gen Sequencing

WebCompared with enzymatic shearing, physical shearing is more tolerant of a broad range of input material; thus, quantitation errors with physical shearing cause less variation in fragment size. Physical shearing is also a less-biased fragmentation method than enzymatic shearing because of the randomness inherent to the mechanical process (Figure 2).
