Content
Please be informed that we have replaced the Strep-Tactin®XT Spin Columns (2-4150-025) with our new Empty Spin Columns. 

Empty Spin Columns are ideal for rapid protein purification from small sample volumes. They are provided with inserted frits (mesh size 10 µm), screw caps, and snap-off plugs and compatible with conventional 1.5 ml or 2.0 ml reaction tubes. The frit in the lower part of the column ensure that the resin remain in the spin column while sample or buffer flow through rapidly during the centrifugation process. The maximum filling volume is 700 µl. The empty spin columns are offered without resin and purification buffer to facilitate a customer-specific application and experimental design, e.g., if specific buffer conditions are required. For purification of Strep-tag®II or Twin-Strep-tag® fusion proteins, the combination with Strep-Tactin®XT 4Flow® high capacity resin is recommended.
