General description
Pepsin is an enzyme found in gastric secretion.
Application
Pepsin immobilized onto agarose beads can be used to digest and then separate out the active peptides of the glycoprotein gliadin.
Pepsin-agarose has been used as an immobilization tool to investigate the refolding ability of the pepsin enzyme. It has also been used for the preparation of F(ab′)2 fragments from rabbit IgG.
Used to produce F(ab′)2 fragments of antibodies.1
Biochem/physiol Actions
Preferentially cleaves C-terminal to Phe, Leu and Glu. It does not cleave at Val, Ala or Gly. pH optimum 2-4. Active in 4 M urea and 3 M guanidine HCl. Stable at 60 °C. Pepsin is irreversibly inactivated at pH > 6.
Unit Definition
One unit will produce a ΔA280 of 0.001 per min at pH 2.0 at 37 °C, measured as TCA-soluble products using hemoglobin as substrate. (Final volume = 16 mL. Light path = 1 cm.)
Quantity
One gram solid swells to 5-10ml packed gel.
