The His-Spin Protein Miniprep provides a fast spin-column based purification technology for His-tagged proteins. Up to 1 mg of His-tagged protein can be purified in 5 minutes and eluted in as little as 100 µl of His-Elution Buffer. The purified protein is ultra-pure and can be used directly for enzymatic assays, protein 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.
