GST SpinTrap™ columns are designed for rapid small-scale purification of GST-tagged proteins directly from clarified or unclarified cell lysates. GST SpinTrap™ columns are suitable for purification of multiple samples in parallel, for example in screening experiments such as evaluation of chromatography media, growth temperature, culture density, and other variables to find optimal conditions for expression.
- GST-tagged proteins can be recovered under mild elution conditions (10 mM glutathione), which preserves the functionality of the proteins
- More than 90% purity can be obtained in a single step
Each column contains 50 μl of Glutathione Sepharose™ 4B, enough for purifying up to 500 μg of recombinant GST and each package contains 50 columns. For increased convenience, GST buffer kit contains stock solutions of the buffers needed for purification of GST-tagged proteins.
