Binding Capacity: Each Spin column can bind upto 250 µg of recombinant protein from 1-5 ml of cell culture or up to 0.25 g of cell pellet. Column Content: Each Spin column contains 100 µl of high performance Glutathione Sepharose beads (Cat # 6555). Bead Content: A 50% slurry (100 µl of settled resin is equivalent to 200 µl of 50% slurry) in 20% ethanol. • Rapid purification of GST-fusion proteins from multiple samples • Optimization of growth conditions for the expression of recombinant proteins • Pull-down of purified GST-fusion proteins for subsequent Western blot (with GST Antibody – Cat # 3997), ELISA and other downstream applications
The expression and solubility of recombinant proteins can be increased by tagging with Glutathione S-transferase (GST). GST-tag binds to glutathione with high affinity and specificity enabling purification of GST-tagged proteins using glutathione-based affinity resins. BioVision’s EZCatch™ GST-Spin Purification Kit is designed for fast, specific and easy purification of such GST-tagged proteins from cell lysates. This kit contains 10 easy-to-use spin columns allowing one-step high quality affinity purification of different GST-tagged proteins. In addition, the kit contains a proprietary Lysis Buffer allowing quick preparation of clear lysates from cell pellets without the need for sonication. Eluted proteins can be directly used for downstream analysis.

Antibodies are affinity purified with an antigen coated column or protein A or G agarose or beads. DNA is purified with endotoxin free silica columns or anion exchange resins. Biovision supplies purification kits and ultra pure reagents.
