    We've found SPRI Select is much more effective than Ampure XP for size selection also. Anybody know what the difference is? I seriously doubt it's the beads themselves...

    Check out this paper. http://www.plosone.org/article/info%...l.pone.0010029

    They use varying percentages of PEG and 0.9M NaCl, not 2.5M. They are also using MyOne CA Dynabeads

      Use TE with 0.05% Tween20 and set it to shake at 37. You may also need to sonicate it a bit to break clumps, but I would not do it if DNA was large

        When you say more effective, you mean the range of the DNA size, distribution or recovery?
