Fast protocol to purify MBP-tagged proteins from cell-free extracts.


  • Fast: Purify MBP-tagged proteins from cell lysates in less than 6 minutes.
  • Simple: Prepare pure protein for small-scale studies using a spin-column.
  • Convenient: No special instrumentation needed other than a benchtop microcentrifuge.


The MBP-Spin Protein Miniprep Kit provides a fast spin-column based purification technology for MBP-tagged proteins. Up to 1000 µg of MBP-tagged protein can be purified in 6 minutes and eluted in MBP-Elution Buffer. The purified protein is ultra-pure and can be used directly for enzymatic assays, biochemical analyses, SDS-PAGE and other sensitive applications. The straightforward spin, wash, and elute protocol dramatically simplifies protein purification and allows the end user to get results in minutes, not hours.

Technical Specifications

Affinity Matrix Amylose Resin
Binding Capacity 100 µl of Amylose Resin typically binds ≥ 400 µg of fusion protein.
Elution Method Excess Maltose
Elution Volume  ≥ 200 µl
Principle of Technology The MBP-Spin Protein Miniprep Kit uses an affinity matrix composed of amylose resin to specifically bind proteins fused to maltose-binding protein (MBP). MBP is known to significantly enhance the solubility of many proteins when fused to them.
Processing Time 6 minutes
Product Storage Please store the Amylose Resin at 4 °C. The other components can be stored at room temperature.
Purity Electrophoretically pure and suitable for enzyme kinetics, biochemical analyses, SDS-PAGE, and other applications.
Required Equipment Microcentrifuge
Sample Type Cell lysates or other complex protein mixtures containing MBP-tagged proteins.
