Protein purification now easier than ever!
PureCube 1-step batch Columns Empty 1-step batch columns are perfectly suited for batch purifications. They can be filled with your affinity resin of choice, and allow for binding, washing, and elution in one single spin column. - For easy and fast protein purification - Multiple purifications in parallel - Require only standard centrifuges - Fully compatible with PureCube Affinity Purification Matrices Designed for small to mid-scale protein purification, the PureCube 1-step batch spin columns save time and pipetting steps. Featuring SelfSeal membrane technology, the column retains resin and sample in a chamber for batch incubation. By centrifugation, the membrane pores dilate and the filtered eluate gathers in the collection chamber of the column. PureCube 1-step batch spin columns are available in two sizes: Mini for expression trials, small-scale screening, and other small-volume purification needs; or Midi Plus for volumes of up to 20 mL.
