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)

Dipeptidyl amino-peptidase 3 (DPP3) is an aminopeptidase involved in peptide degradation, including hormone peptides as angiotensin II and enkephalins. DPP3 plasma activity increases in septic patients and correlates with mortality risk. However, the exact physiological role of DPP3 remains unclear
