Applications:

Reduced glutathione is covalently linked 4B for use in affinity purification of glutathione-S-transferase (GST) and GST-fused proteins. Glutathione Super Flow (SF) is used for protein purification by batch/column and scale-up procedures. Glutathione Super Flow (SF) has an exellent protein binding capacity. The good flow properties of the 92 μm (average size) highly crosslinked matrix makes an excellent choice for protein purification by column purification or batch process for scale-up.

This product provides a one step purification method and permits rapid, mild and highly selective purifications of proteins containing glutathione binding sequences. Glutathione-Separopore is prepared by covalently coupling glutathione to epoxy-activated 4% crosslinked agarose beads to form a stable thioether linkage. The coupling was optimized to give a high binding capacity of 5 mg or more of Glutathione-S-transferase (GST) per ml of wet gel. Bound GST–fusion proteins are easily displaced from the resin by elution with buffers containing reduced glutathione. Mild elution conditions preserve protein antigenicity and function.
