Strep-Tactin® MacroPrep® resin
50% suspension to purify Strep-tag®II or Twin-Strep-tag® fusion proteins
Please note that this product will be discontinued. Strep-Tactin® MacroPrep® resin will still be available until 31st December 2024 or as long as stock lasts.
Strep-Tactin® MacroPrep® consists of polymethacrylate, a synthetic material coupled with the streptavidin variant Strep-Tactin® and is applicable for purification of Strep-tag®II or Twin-Strep-tag® fusion proteins. In contrast to agarose resins, plant cell components such as chlorophyll are not unspecifically bound by this resin, which makes Strep-Tactin® MacroPrep® the favorable alternative. The suspension can be used for packing of gravity flow columns since the resin is optimized for column affinity chromatography, rather than for batch purification. To pack a column with 1 ml resin bed volume, 2 ml 50% suspension are necessary.
