This material is sold by the final volume of gel produced after swelling of the powder. One gram of powder swells to approximately 14 mL of gel. (Approximately 70 mg of powder swells to 1 mL of gel.) Swell the lyophilized powder in deionized water (use of some buffers can result in non-recoverable loss of volume) at 200 mL/g. Typically 90 to 95% of swelling occurs within 30 minutes at room temperature, but it may require overnight at 2 to 8 °C for 100% swelling to occur. After swelling, the agarose beads must be washed thoroughly with 10 volumes of water or equilibration buffer (such as PBS) to remove the lactose present in the lyophilized product.
This product consists of glutathione attached through the sulfur to epoxy activated 4% cross-linked beaded agarose, resulting in a 12 atom spacer. Binding capacity: approx. 5 to 10 mg glutathione S-transferase per mL resin.
After the resin has been swollen, it can be stored in 2 M NaCl at 2 to 8 °C. For long-term storage, a bacteriostatic agent such as 1 mM sodium azide or 0.02% thimerosal should be included. Alternatively, the resin can be relyophilized after addition of lactose.
Regeneration method:1. Wash with approximately 5 resin volumes of 0.1 M borate buffer, pH 8.5 containing 0.5 M NaCl (Cleansing Buffer 1).2. Wash with at least 5 column volumes of deionized water.3. Wash with at least 5 column volumes of 0.1 M acetate buffer, pH 4.5, containing 0.5 M NaCl (Cleansing Buffer 2).4. Wash with approximately 5 resin volumes of deionized water. For long-term storage, store in 2 M NaCl containing a bacteriostatic agent.5. Equilibrate with equilibration buffer before use.
Tris or phosphate buffers (pH 6.5 to 9.5) are typical lysis buffers compatible with glutathione affinity chromatography. Salt concentrations of up to 1 Molar do not interfere with binding. Protease inhibitors such as EDTA (Product No. E7889) or PMSF (Product No. P7626) are often included in the lysis buffer. Serine protease inhibitors included in the lysis buffer will not interfere with subsequent thrombin or factor Xa treatment as these inhibitors are removed before the proteolysis step. The binding of GST to glutathione-agarose is unaffected by 1% Triton X-100, 1% Tween-20, 1% CTAB, 10 mM DTT or 0.03% SDS.
