General description

Sepharose® 4B is an agarose bead and a polymer of Gal β1,4 [3,6]-anhydro-L-galactose. Sepharose aids in fractionating larger molecules and is devoid of charged saccharides. Presence of 3,6-anhydro-L-galactose resists biological degradation. Hydrogen bonds stabilize the sepharose gel structure. Sepharose is widely used in affinity chromatography by cross linking various ligands on the matrix.

Application

Sepharose® 4B has been used:
  • to conjugate scorpion venom to be used in affinity chromatography
  • for clearing of protein extracts prior to immunoprecipitation
  • for gel purification and desalting of phospholipid vesicles
  • for adsorption of immunoglobulin G (IgG)
