Understanding the Science Behind Glutathione Sepharose 4B

Glutathione Sepharose 4B is designed for the single-step purification of glutathione S-transferases, glutathione-dependent proteins, and GST-tagged fusion proteins.2007年2月2日—GE Healthcare's Glutathione Sepharose 4Bis an affinity chromatography medium which has affinity for GST and other glutathione binding proteins. The core of its functionality lies in the covalent coupling of glutathione ligand to a 4% agarose matrix. This specific matrix is crucial, forming the basis of the bead structure that facilitates the purification process.Glutathione Sepharose High Performanceis recommended for high-resolution purification of GST-tagged proteins, providing sharp peaks and concentrated eluent. The bead form is typically spherical, with an average bead size of approximately 90 µm for Glutathione Sepharose® 4B, though other variations exist, such as the 45-165 µm wet bead diameter noted for some formulations. This controlled particle size is vital for optimal flow rates and efficient binding.This product provides a one-step purification method and permits rapid, mild and highly selective purifications of proteins containingglutathionebinding ...

The ligand, glutathione, is attached to the agarose beads via a spacer arm. In the case of Glutathione Sepharose 4B, this spacer arm consists of 12 atoms (10 carbons).Glutathione Sepharose 4B may be regeneratedfor re-use by washing the gel with 2–3 bed volumes of alternating high pH (0.1 M Tris-HCl + 0.5 M NaCl, pH 8.5) ...
