Zymo Research has a wide range of DNA size selection kits to choose from that provide a fast and simple solution for purifying specific ranges of DNA fragments from PCR, endonuclease digestions, ligations, library preparations or agarose gels. The Select-a-Size DNA Clean & Concentrator kits allow for specific fragment size cutoffs that can be modified to suit reaction clean-up, left-sided, right-sided or even double-sided size selection. Simply choose a desired cutoff to bind the target fragment of interest onto magnetic beads or spin-columns by adjusting the provided binding buffer. The Zymoclean Gel DNA Recovery Kits enable the rapid recovery of highly concentrated DNA fragments of various sizes from agarose gels using proprietary binding chemistry and a micro-elution spin column. The Select-a-Size DNA Kits and the Zymoclean Gel DNA Recovery Kits yield high-quality DNA that is suitable for highly sensitive applications including next generation sequencing, cloning, and PCR.
