WebIn order to release ALL of the plasmid DNA, ALL of the cells need to be lysed. To do this, make sure the cells are resuspended completely, without any clumps, and incubate the cells for the recommended amount of time. DON’T vortex your cells after lysis Vortexing can cause shearing of host chromosomal DNA, resulting in gDNA contamination. 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
