Proteus 1-step Batch Midi Plus Spin Columns

Proteus 1-Step Batch Midi Plus Spin Columns are designed for small scale protein purifications such as those required for expression trials, solubility determination tests, screening, tittering and scouting studies. These innovative columns incorporate a SelfSeal™ membrane technology which retains the resin and sample in the batch incubation chamber. When the column is spun in a benchtop centrifuge at 750 g, the pores of the membrane dilate and the filtered eluate is collected in the bottom of the centrifuge tube.
