Can several extraction steps be performed in the same MaXtract tube?

Yes, if a sufficiently large MaXtract tube has been selected for the extraction it is possible to perform multiple purification steps in this tube. Sample and organic solvent are placed in the MaXtract tube, mixed and centrifuged. Organic solvent is then added again to the aqueous phase separated by the gel, followed by mixing and centrifuging. Following the last extraction step, the sample is transferred to a new tube for storage.

For the purification of samples with high protein content, we recommend using a new MaXtract tube for each extraction step.
