WebOver-shearing gDNA may impact amplification and the yield of the final size selected SMRTbell library. It is, therefore, critical to work with samples where the majority of the starting input genomic DNA is greater than 20 kb and if necessary, optimize the shearing conditions to obtain the 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). WebThe two most common methods of DNA fragmentation for generating random double-stranded breaks without base bias are sonication/acoustic shearing, using … cswffl
